An IT Manager's Tale

Fine tuning BSPWM

noreply@blogger.com (Phil Mulley) — Tue, 15 Sep 2020 21:04:00 +0000

I've been using BSPWM for some time now. I had been rather bored with making the normal setups/configs for standard window managers for my linux boxes and started to look at tiling window managers rather than all in one desktops.

Eventually this lead me to BSPWM (via quite a few of the others, honourable mentions to Awesome & Qtile) set off with a nice polybar panel.

Here's what it looks like now:

I've played around with it quite a bit (not short of time these days!) even setting up a script to use rofi to display all my keyboard shortcuts.

I used a base of ArcoLinux which I highly recommend: they have builds for almost all the nicer tiling window managers right out of the box: and its easy to mix and match if you want to do that.

The only real problem I've had was setting things up so that particular applications always worked on particular desktops. Until I used a tiling WM I never really saw the point of desktops: but they are so practical and easy to use in a tiling setup. Once I started using them I wanted to automate things so that I would always know the quickest way to find the window I was after.

This is rather more difficult in BSPWM than I'd hoped.

You need to edit your main config file for BSPWM to get these settings sorted: when you open up bspmwmrc with your text editor its easy to find the correct section to start looking at: (assuming you got a leg up as I did with much of the initial config coming from Arco) but quickly I found that many of my extra lines to specify desktops for particular programs were not working. I did a deal of googling around which did lead to some results: but it seems inconsistent: working for some things and not for others.

Anyway after much mucking around I include the section of code with my working setup: so you can copy some of these and use them for yourself without having to go through all the hoops I had to to get this working.....

Fixing an unreliable NFS mount

noreply@blogger.com (Phil Mulley) — Fri, 08 Feb 2019 23:45:00 +0000

I store my music, photos and documents in a central location so that I can access them via any of my systems.

Since I don't use any windows systems at home I can use NFS as a sharing method rather than SMB (or SAMBA).

This has always meant that the share seems quite a bit faster and more reliable. Recently, however, the mapping as set out in my /etc/fstab file has not always been working. Sometimes I get a waiting symbol rather than the regular icon for network manager just after logon: and on these occasions I find that the mapping has not been done.

After some research I found a package that fixed the issue for me (given that I use network manager).

The fix involves enabling a service on bootup:

systemctl enable NetworkManager-wait-online.service

Setting up a music player using PiCorePlayer and Bluetooth speakers

noreply@blogger.com (Phil Mulley) — Sat, 26 Jan 2019 16:26:00 +0000

I've used LMS (Logitech Media Server) for quite some time. I stared off running it on a windows machine many years ago. It was where I already had my music files and the service seemed quite light running.

I'd been on the search for an easy way to play my MP3s via my stereo system rather than my crappy computer speakers for ages. The Logitech range of hardware helping you do so seemed ideal.

I started off with the Squeezebox Duet:

As you can see you have a rather nice remote with just enough screen to show off your lovely album art and another small box: which turns out to be the interface between your data (in my case on the computer connected through the network) and my stereo system.

Joy abounded: for quite some time. And then.....well the hardware got older. I stopped using the remote because it kept disconnecting and the battery degraded. So, when setting things up again I had to configure the squeezebox in a headless fashion as I was no longer using the remote: it can be done, but easy its not. If anyone is interested in how this is done: comment on the piece and I'll see if I can remember.

Then (still aeons ago!) I moved over to Linux, so I needed a way of keeping my system going using a new operating system for the server.

My home server runs on vanilla debian: and there is a version of the server software which runs just fine on there : after some persuasion. So, once you get the service running you can do the rest from the web interface:

To bring things up to date, this was all fine, but it only connected to my main stereo in the front room.

For my bedroom upstairs I had a squeezebox radio:

This worked fine, and doubled up as a handy alarm clock too.

However, the darn thing gave up the ghost a short while ago leaving me bereft of sounds upstairs.

So, in went my old LED alarm clock again (I convince myself it has a retro look) and I started to look at alternatives.

I've long been a fan of all things Raspberry Pi and as a result of this I had an old Pi 2 lying around not doing anything.

This is easily fast enough to convert into a standalone player which can expand your already existing LMS ecosystem.

I've tried a number of music players running on this Raspberry Pi 2 before (because its fun and I'm sad) but I settled on PiCorePlayer this time.

My plan was to get up to date and use a bluetooth speaker with the player. To this end I chose a soundbar eventually, in fact this one, the Azatom Studio Soundbar 2.1. Its not bad, for the approx £50 I shelled out, but nothing special.

So: how to do it?

The Build

Download the image file you require first. As of writing, this can be found here
Write the image file onto your SD card that is to be placed into the Pi. You really don't need a large SD card, 4GB would be easily big enough. Remember, we are not putting any music on this thing, that stays on the server. I used USB image writer on my distro (currently ArcoLinux Openbox) to write the image onto the card.
Put the SD card into the PI.
I added a bluetooth dongle via USB so the Pi could connect to the soundbar. The one I used was a Rocketek, and it seemed to work fine. I did check first and Amazon suggested it was fine to work with Linux and a Pi.
The Pi will need to connect to the network (to find the server service and also "see" the music files) so I connected it via ethernet. I've read warnings about using WiFi and bluetooth concurrently in this setup, so a good old wired connection seemed a good idea (it was).
Googling around suggested that the newest versions of PiCorePlayer would now work with bluetooth connections so once I had my hardware connected together I fired the thing up.
This is another piece of hardware with a web interface, but to use this you need to know its assigned IP address. I found this out by going into my router and looking at what was currently connected to the network.
Once you know the IP you can open up your browser and check out the interface. Once you are in, click on the button labelled "main page" and have a look at the bottom of the page. Here, you will find a way to display the more exotic controls via the "beta" controls, so make sure you have this selected as below:

By default only the player software "squeezelite" will be running. You can use the PiCorePlayer to run a full version of LMS and make the unit a whole sound system in itself. I've done this before with great success, using a USB stick attached to the PI to hold the MP3 files. However, for this example we just need the player running.
Lets have a go at setting it up. My first port of call was expanding the image on the SD card so that the software could make full use of the space available on the SD card. There's a button for this on the interface under "main page" and "advanced mode operations": like this

I decided to get everything up to date next, so I did an update. This is also on the main page, under "main Pi Core operations":

With this done, its a good idea to give it a restart. You can see the button for this in the picture above as well.
You may want to take one of the other options on these dialogs as well: to set a fixed IP address for the player: this means that if you need to get onto the interface in the future, you don't have to go rooting around in your router's settings to find its IP again.
Given we are using an ethernet connection in this example, I wanted to turn the WiFi off. This is quite easy as you can see below:

Now we need to see if we can get things going with bluetooth. This was the bit I was afraid of, TBH. I had done quite a bit of googling around in preparation, but the help available on this was rather spartan as its quite a new feature. There are some help pages available from the PiCorePlayer people, but I was getting confused.
I worked out that I had to change the output of the squeezelite player, but only after I had enabled my bluetooth setup. There were references to the "squeezelite settings" tab on the interface, but I couldn't for the life of me find where I could input these settings.
Eventually I did twig it: there is a small box labelled "Card Control" and that is where we have to head:

If you actually click on this box (which was non obvious, to me) you see:

If you study the picture above you'll see that my bluetooth is recognised, as is the soundbar (you can see that in the picture above and the one above that, too), but the devices are not currently connected. You need to click on the "scan" buttons to get the bluetooth on your Pi to "see" the soundbar.

Conclusions

Its quite a nice setup, the Pi is tiny and can be kept out of the way (although not too far from the bluetooth device you want it to connect to) and it seems to run for ages with no errors.

I run OrangeSqueeze on my android phone and tablet, and on that you now only have to swap players to output music from the Pi to the bluetooth speaker.

For music enthusiasts: you may wish to get a better bluetooth speaker than I did with my soundbar. I'm not attacking the Azatom device here, for the price I paid its excellent: but I would have liked something with slightly higher quality sound and a more reliable bluetooth connection. I get bluetooth cutting out occasionally, but its not a deal breaker at this stage.

Thoughts on the TP-Link RE200 Wireless Booster

noreply@blogger.com (Phil Mulley) — Sat, 12 Jan 2019 14:34:00 +0000

A little while ago I went over to a friend's house to install at TP-Link RE200 wireless booster as his wireless signal gets pretty weak upstairs.

It all turned into a bit of a saga.....

In theory it should have been a doddle. All I needed to do was to go through a simple WPS process to get the RE200 talking to his existing router and all should have been well.

Initially things looked like they were going well, once the WPS buttons had been pressed on both router and the RE200 lights started turning on and my hopes were high. However, only 2 of the lights on the range extender came on and when I tried to connect to the new wireless network I could not get an internet connection.

So I gave up on WPS and looked at the "manual method" as suggested in the paperwork that came with the product. This involves disconnecting from any current wireless network and connecting a laptop (or other device) to the RE-200. When you turn it on it will create a wireless network of its own, called something like TP-Link_Extender. At this stage you are supposed to open a web browser and to go to http://tplinkrepeater.net or http://192.168.0.254. At that stage you should be able to use the router's credentials to log in: then you can further configure your RE-200. I was just not getting any reply from either page.

After much googling (and even more muttering and chuntering from myself) I finally sorted out what had happened.

My friend's router was giving out addresses in the 192.168.1.x range but the extender wanted to use an address on the 192.168.0.x range......so they were not talking to each other.

So if you come across something similar: there is a way round the issue. Turn on your extender and let it settle down for a minute or so. They you will need a laptop and an ethernet cable. Disconnect any automatically connecting wireless connection that may have started with the machine. Run the ethernet between the laptop and the RE-200. Now you will need to check to see what IP address is being given to that connection to the ethernet port of your laptop. Chances are, if you are having the same issue as I had, the address will be in the 192.168.0.x range. Assuming your router is working on the 192.168.1.x range then you will need to set a static address on this port so that you can get things going. I was using a windows laptop so I could just right click on the connection and change its properties. You can do the same in linux with network manager. I gave the connection the address of 192.168.1.253 as a static IP and then disconnected the cable and rebooted the RE-200. You can then connect it up again and with the ethernet between your laptop and the RE-200 you should now be able to get onto the webpage via its ip address, ie http://192.168.1.253 : now finally you will get the prompt for the router's authentication and once you enter this you will be able to see and alter its settings via the web interface. I went straight into its network settings and changed them all round to reflect the new IP range and at last, the range extender was talking properly over the network and its 2 new wireless networks had proper access to the internet.

So, all in all, a bit of a pain in the backside, to be honest. To be fair to TP-Link there have been no issues with the unit subsequently. I checked out their support site and there does seem to be a quite new firmware package for the RE-200. Once of the fixes listed for this new firmware is: "Fixed the issue that extender can't obtain IP address in a few special situations" so perhaps newer units will not suffer from this annoying defect. There is no real reason why the device could not adjust to different IP ranges used by different routers (as its competitors seem to do without bother) so this is consumer unfriendly to say the least. I've had good experiences in the past with TP-Link products so I don't wish to be overly critical: but this is something that should be fixed for the sake of the less technical users out there.

New look for my Plasma

noreply@blogger.com (Phil Mulley) — Fri, 16 Jun 2017 12:53:00 +0000

I've settled on the breeze dark "look and feel" for some time now.

I did try ark dark because I loved ark dark in my GTK desktops and I particularly like the window decorations.

However, going through all KDE's extra options to try to get GTK apps to display the same as native QT I could never get the consistency I was looking for, so back to breeze dark.

These are the look and feel themes I have installed currently:

Setup like this I did have the consistency I was looking for but I wanted something more.

Breeze dark with a little transparency would be even nicer: so I delved into the nether reaches of the "get new theme" button and came up with Breeze Transparent Dark, which does the trick nicely.

Here are my installed desktop themes:

Now I can have some lovely effects on my menu and taskbar:

I've moved back to KDE with Antergos

noreply@blogger.com (Phil Mulley) — Thu, 08 Jun 2017 13:56:00 +0000

I had a bit of a disaster with my Manjaro XFCE and despite my best efforts I could not revive it. If you watch a lot of YouTube videos on linux distros you often see people starting off on Manjaro and then leaving it when something goes wrong. Usually, its Manjaro that gets the blame. So, just to be clear, this was all my fault: nothing to do with the distro.

I'd decided to fiddle around with my graphics settings to try to reduce screen tearing and after putting in some extra settings on the nividia-settings module life got awfully nasty. Initially I had no visuals at all: but after a bit of terminal work I did get the GUI back: but Steam in particular refused to play ball despite my frantic googling efforts.

This seemed a good opportunity to try something new: so I decided to have a look at KDE again. I like KDE: I like the way you can fiddle around with all aspects of the desktop to your heart's content. It also gave me the excuse to put another 8GB of RAM in my tired old HP desktop taking it up to the giddy heights of 16GB.

I decided to go for a "purer" Arch with Antergos rather than stick with Manjaro (although they do a KDE version) so with some trepidation I set up the ISO on a trusty USB stick and off I went. In the past I've had all sort of fun and games with Antergos and in particular, the installer. However, on this occasion I did get the install completed after some playing around with the updater which did eventually update the running ISO and do the install.

Its my first serious go (I don't count virtualbox) at KDE 5 and its a bit of a revelation. In common with other commenters I've found it far less resource intensive than I had expected. Of course it does use more RAM than XFCE (which I still use on a laptop via the ever reliable MX-16) but it seems far better than my previous installs.

Here's what I'm rocking now:

This is with my trusty NVidia GT-640. I do have a much better NVidia card but its too power hungry for the PSU in the HP plus its too big for the motherboard: so that one will have to wait for a new build for now.

I experimented with quite a few themes (as you do) but settled on breeze dark in the end. I do love the arc-dark look, especially the window buttons, but I just couldn't get it to look consistent between the normal and GTK windows so in the end I gave up and went for breeze in look and feel and desktop themes.

I have to say I'm well pleased with the results: and it does perform well as a gaming rig too. I've just added Mad Max to my steam library and despite its dire warnings of performance issues on first run: it does run just fine: even with antialiasing on.

Update

I've just updated my Mad Max to use the vulkan driver that's available via the Steam beta: and the results are fantastic.

Delay the startup of Latte Dock in KDE

noreply@blogger.com (Phil Mulley) — Fri, 19 May 2017 10:57:00 +0000

I'm now using a KDE build (Antergos) : and loving it!

I've been using Latte Dock since I had some issues with Plank under KDE: on occasions it would show an extra icon for Plasma and that started me looking for something new.

I do like Latte Dock a lot: but I've been having an issue with KDE occasionally crashing out of GL compositing on startup: which always shows up in the dock since its background re appears and looks ugly.

My theory is that if I could delay the dock startup a while: the compositing would be unaffected when the dock loaded: and so far it seems to have worked.

So I changed the line in my autostart to look like this:

The only thing I changed was the command which reads:

sleep 20s && latte-dock &

Now the compositing can load ahead of the dock and all seems to be well.

Strange Mouse Effects with Virtualbox

noreply@blogger.com (Phil Mulley) — Fri, 16 Dec 2016 16:10:00 +0000

Since the latest updates to Virtualbox I've noticed a strange issue with the mouse pointer on the guest systems.

I usually run Linux VM guests but I've read reports that this can be an issue with windows guests as well. A very large and annoying pointer shadow appears on the screen:

I've googled all around and tried a few fixes but nothing works for me so far. Plenty of other people seem to get this issue, but there are no workarounds that have helped my situation.

The issue seems to vary in severity according to the mouse pointer scheme you choose, with plain black pointers its much less pronounced but if you are using the chameleon cursor set you are really out of luck.

If anyone knows a fix: please let me know.

Freetype update issue from the aur

noreply@blogger.com (Phil Mulley) — Fri, 16 Dec 2016 15:58:00 +0000

If you use the infinality font set one of the fonts you get is Freetype.

Recently when updating I found there was an issue with updating this package, which was from the AUR on my manjaro.

The update was failing and coming up with an error which complained about the PGP key in the update.

As always google is your friend, and it lead me here

It turns out that you can refresh the required key with this command:

gpg --keyserver hkp://pgp.uni-mainz.de --recv-keys 58E0C111E39F5408C5D3EC76C1A60EACE707FDA5

Once that was done the update went through without an issue.

Infinality Fonts and text antialiasing issue

noreply@blogger.com (Phil Mulley) — Fri, 16 Dec 2016 15:51:00 +0000

I always set up the infinality fonts when I set up a Linux distro. Its not that Linux is awful at fonts, but its hard to argue its always as good as windows. If something can be improved with regards to a linux config, I'll have a go.

Until now I've never had an issue with the infinality fonts which I use both in Manjaro and MX15/16. However, the other day I did come across something rather strange.

I was trying to set up a logo for my sister's blogsite and I wanted a clear background with the text on top. So I googled how to do this with gimp and off I went: but when I typed in my logo this is what I saw:

The green highlight around the edge of the font was hideous, so I had to go another way.

So off to google I went and eventually I found this

The solution was this:

Creating /etc/gimp/2.0/fonts.conf and adding

fixes the problem.

Getting my Manjaro to look just right

noreply@blogger.com (Phil Mulley) — Tue, 24 May 2016 12:07:00 +0000

I use Manjaro (main XFCE edition) on my main desktop machine, a second hand HP 6000 Pro bought for around £150 a year ago, upgraded to 8Gb RAM and now running a moderate Nivida video card.

Its been running fine with just the odd hiccup since then.

I'm generally a fan of the dark themes and I do like a bit of Compiz (I'm a sucker for the wobbly windows). I went with the manjaro-compiz package and I run it at startup using the Compiz Fusion Icon.

A consequence of this is that you end up redoing a lot of your settings again in compiz settings manager. For example: I had to set new keyboard shortcuts for minimizing and maximizing windows. One annoyance is that if you go this way you lose windows snapping. The addon for wobbly windows conflicts with the one for snapping via CCSM and I chose my good old wobbly windows. I'd like to have both.

Now that we have GTK3 coming in things change again.

Manjaro have recently updated pamac, their app for updates and installing packages that runs as default in the main XFCE edition.

This means that I need a theme which can deal with GTK2, GTK3 and Compiz.

If you have had Manjaro running for a while you will of course have had all the updates but you may still be on the first theme that came with your initial install and that is the Menda theme. I moved away from this when I had some issues with it and GTK3. The solution is the great new theme that now comes with Manjaro : Vertex-Maia. This works great with GTK3.

I used to use Emerald theme manager for Compiz but I've gone back to GTK for the window decorations.

However, when you do this you'll find that the window decorations (the look for the maximize, minimize & close buttons) are not consistent with the theme.

I found the solution in the Arch WIKI:

Selecting the theme in Compiz 0.9: The 0.9 version of GTK Window Decorator will read Metacity's theme settings from GSettings. The theme can be set with the following command:

$ gsettings set org.gnome.metacity theme theme-name

where theme-name is the name of the theme you wish to use.

Selecting the theme in Compiz 0.8: The 0.8 version of GTK Window Decorator expects Metacity's theme settings to be stored in GConf. Despite the fact that Metacity no longer uses GConf, the GTK Window Decorator theme can still be set using the following command:

$ gconftool-2 -s /apps/metacity/general/theme -t string theme-name

where theme-name is the name of the theme you wish to use.

I'm using vertex-maia as my icon theme as well. I use the dark variant of the main theme, the package is: Vertex-Maia-Dark.

Here's what a normal window looks like:

And Pamac is now pretty consistent in its GTK3 guise:

I think the theme looks great on the start menu as well:

I think the background is of of Charlie Henson's excellent backgrounds.

Finally: the GKT Greeter: if you had the old menda theme and then are moving to Maia then you will need to look at this too.

Get in via the "all settings" manager and click on:

Now make sure that you have the new theme selected in there instead of the old menda one:

Finally lets consider LibreOffice. It works fine with a dark shell but the icon set used is not the best by default. I like the breeze and sifr icon sets available to LO but the standard ones don't show up well on a dark theme.

To get round this you may want to look up libreoffice-breeze-icons in the AUR. This will allow you to install a special set of adjusted icons:

You can now select the icon set from within settings in LibreOffice Writer:

And this is how things should look now in LO:

Logitech Media Server memory mangement under Linux

noreply@blogger.com (Phil Mulley) — Sun, 31 Jan 2016 10:51:00 +0000

I've had a Squeezebox up and running for many years. Its served me very well in that time, and although admittedly a bit "techie" for all tastes it runs well and has been reliable over the years.

Around a year ago the NAS I was holding the data on and running the server software from (ancient Netgear ReadyNAS NV+ running sparc) died a sudden death. Despite many attempts I could neither revive the NAS nor even get the data back from it.

I did have some backups and other sources for getting the data back, and after a few weeks I had amassed most of it again, thank goodness. All those hours of burning CDs, filling in MP3 tags and finding appropriate album images had not been wasted.

I have an old Dell machine running in a small area I laughingly refer to as an "office area" and I thought: since its almost always running: why not use this as a media server instead. So I went ahead and installed the linux version of the Logitech software on there and then added a 2nd hard drive and copied over my music and photos.

After a good deal of fiddling around the setup seemed to work well: except for one thing. A huge memory leak! Within a week of a reboot the machine (Dell Vostro 200 with 4GB of RAM) had pretty much run out of memory.

A few days ago I came across a YouTube posting by Joe Collins which was talking about memory management under Linux.

He mentioned this command:

sudo sh -c "sync; echo 3 > /proc/sys/vm/drop_caches"

I ran this on the machine and lo and behold: back came some free memory.

The next job was to schedule this to run regularly: otherwise the freed up memory would slowly disappear again.

So I created a cron job to facilitate this.

Since the command was preceded by "sudo" I needed to edit the root contab file in order for it to run so the command was:

sudo crontab -e

This command takes you into the appropriate file to edit (after choosing your editor, in this case I chose NANO).

At this point you need to enter some syntax into the file which firstly tells cron how often you want the command to run and secondly gives it the command to run.

In my case the command was:

*/120 * * * * sudo sh -c "sync; echo 3 > /proc/sys/vm/drop_caches"

The first bit (*/120 * * * *) tells cron to run the job every 120 minutes, and the 2nd is our command.

No more reboots to reclaim memory for me!

Clean shutdown for Manjaro from a keyboard shortcut

noreply@blogger.com (Phil Mulley) — Sun, 07 Jun 2015 22:11:00 +0000

I always like to shut down my computer using a keyboard shortcut rather than the GUI. For me, its just faster and its one of the things I set up in all new linux setups.

The command I always used to achieve this was:

dbus-send --system --print-reply --dest=org.freedesktop.ConsoleKit /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Stop

However, recently I found that this stopped working.

When I ran the command from a terminal I found the following error:

The name org.freedesktop.ConsoleKit was not provided by any .service files

Eventually I found a post on the ubuntu forums (referencing their french forums) which suggests that this no longer works and to try instead:

dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 "org.freedesktop.login1.Manager.PowerOff" boolean:true

When combined with a keyboard shortcut this works perfectly again.

Power saving and the kernel on a Dell Vostro 200

noreply@blogger.com (Phil Mulley) — Tue, 05 May 2015 09:02:00 +0000

The power saving features on the Dell I've been using for a while have been bothering me for a while. Its running Mint 17.1 cinnamon and has always had a few issues with sleep. I tried all sorts of permutations but left on its own the machine always crashed after a while: when going into power saving mode.

I've not totally sorted it: but I have found a parameter to add to the kernel startup which helps quite a bit:

quiet splash acpi_backlight=vendor

You'll probably find using grub customizer the easiest way to test this parameter.

In praise of Kobo

noreply@blogger.com (Phil Mulley) — Mon, 02 Jun 2014 11:28:00 +0000

Around about 3 years ago I was given a Kobo E Reader by my brother in law as a birthday present (it could have been Xmas but I digress....). The choice was actually mine but he bought it.

I chose Kobo at the time because I wanted to avoid the ever present Kindles and I was worried about Amazon cornering the market in E books with their proprietary formats and readers. I also liked the idea that they were available here in the UK at WH Smiths who have a branch locally and I remembered from my childhood.

As time went by I found I used the Kobo quite a lot although mainly when I was on the train to work. I bought quite a few books from their store and also downloaded some of the classics that were available for free. I kept updating it as new firmware came out and all seemed well.

Around 6 months ago the Kobo started to play up a bit. I found that it would no longer mount as a separate drive when attached via USB to a computer and it seemed a little bit slower. I had backed up my books to a computer and the ones that were bought from the Kobo store were always available via their web portal and online store but I worried that I would lose my content eventually.

So with a heavy heart I contacted their online support people and started a long correspondence aimed at fixing it. Despite our mutual best efforts it appeared that all was lost and the Kobo was going to fail.

Then to my surprise they offered to replace the Kobo for free (apart from some shipping charges to Europe which to be fair were probably in place to stop jokers trying to get something for free). I am now the proud owner of a shiny new replacement Kobo!

So praise be to Kobo. My cynicism was misplaced and it only seems to give praise where its due. If you are in the market for an E reader perhaps this will give you some more confidence to go with the Kobo instead of a Kindle and together we can at least put off yet another monopoly for a while.

Get an up to date version of Clementine for your Debian based setup

noreply@blogger.com (Phil Mulley) — Sun, 23 Jun 2013 15:50:00 +0000

My favourite linux audio player is Clementine.

You can get this in the debian repositories but its a bit out of date: but there is an extra repository which is much more up to date and works a treat with debian, here.

noreply@blogger.com (Phil Mulley) — Sun, 23 Jun 2013 15:47:00 +0000

I am a big fan of the latest version of XBMC : frodo (version 12).

If you are using an Ubuntu based distro then you can get hold of this latest version with no problems.

If, however, you are using a Debian based distro, such as the excellent SolydXK or the also excellent Crunchbang then you are stuck at version 11. Apparently debian did not like some of the non FOSS eliments used in the newer version so its not in their repos. I make no critisism of Debian for that, that is their philosophy and they are entitled to it.

If, you are still after version 12 on a Debian distro: what to do:

Well....head over here

Quite a bit of that page is in German, but fear not, the important bits are in English as well.

I tried to set this up under Crunchbang a little while ago and had no success, but yesterday I tried again with SolydXK and it seemed to work just fine.

This is what I did.....

wget http://debian.oppserver.net/gpg-debian.oppserver.net-signing-pubkey.asc -O - | sudo apt-key add -

sudo su -c 'echo "deb http://debian.oppserver.net/xbmc/ wheezy main non-free contrib" > /etc/apt/sources.list.d/oppxbmc.sources.list'
sudo su -c 'echo "deb-src http://debian.oppserver.net/xbmc/ wheezy main non-free contrib" >> /etc/apt/sources.list.d/oppxbmc.sources.list'
sudo aptitude update

Update: May 2016

These days life is a little easier for those who wish to mix a bit of debian with XBMC (nowadays Kodi).

When I build machines for those very new to linux who need reliability above all I now use MX-15. It uses the stable debian repos by default and yet it has the latest version of XFCE (4.12 at time of writing) powering things.

I recently had a brief forum exchange on using Kodi in MX-15. It turns out if you want to do this: don't enable the debian multimedia repos as they carry an old version of Kodi. I had done this and also given the debian multimedia repos a higher priority: so when I searched in Synaptic for Kodi all it found was the old version.

MX-15 now carries version 16.0 of Kodi in its stable repos, and 16.1 in its testing repos: so you can have the best of both worlds.

Consistent mouse cursors with XFCE

noreply@blogger.com (Phil Mulley) — Sun, 23 Jun 2013 15:37:00 +0000

This is one that has annoyed me for quite some time: so when I finally found a solution I was delighted.

The issue is that when you change your default mouse theme under XFCE it does not appear to change completely: run firefox for example and take your cursor up to the top of the window and you will find that the cursor changes back to its old default. All rather annoying....

However: thanks to the good people at makandra a solution is at hand:

Go to your terminal and type this in:

sudo update-alternatives --config x-cursor-theme

You can now choose to assign the theme globally.

You will need to log in again for the changes to take hold: but at last, consistency is yours!

Setting up a website for a friend

My English House

For the past few days I have been working on setting up a site for a friend of mine. He wants to do some additional work as an English tutor working over the internet giving lessons via Skype.

I decided to use blogger and a nice template: and so far things are going well.

Here is a link to the site : its also under links on my homepage.

If anyone has any suggestions on site design etc: please go ahead and let me know.

Linux menus and the Windows Start Key

noreply@blogger.com (Phil Mulley) — Sat, 23 Mar 2013 22:21:00 +0000

Linux menus and the Windows Start Key

Linux distributions like Ubuntu open the main menu with Alt+F1 instead of the Windows key that most new Linux users would be expecting, but it used to be simple to change the shortcut key. Since Ubuntu 9.10 the process isn’t so obvious, but we’ve got the instructions for you.

Just in case you’re a total newb, here’s the menu we’re talking about: (see above)

Change the Gnome Main Menu Shortcut Key to the Windows Key
The first thing you’d normally do is head to System –> Preferences –> Keyboard Shortcuts to change out the shortcut key, but sadly the “Show the panel’s main menu” can’t be assign to the Windows key. You can hit the key as much as you want, but it won’t work here.

What you’re going to need to do is either open up a terminal or use the Alt+F2 shortcut key to bring up the Run Application dialog, and then paste in the following:
gconftool-2 --set /apps/metacity/global_keybindings/panel_main_menu --type string "Super_L"

Once you’ve hit the enter key, the Windows key will not only open the main menu, but the Keyboard Shortcuts panel will be updated with “Super L”, which means the left Windows key

And there you go.

Update

I'm a fan of XFCE and one of the main reasons I like it is that its the only desktop that I know of that is compatible with the lovely whisker menu.

If you want to launch this menu with your windows key this (from the Codeyarns Site) should get you going:

Go to Settings -> Keyboard -> Application Shortcuts. For the command xfce4-popup-whiskermenu, change it to the Win key.

Set up a Fog server for open source image deployments

Set up a Fog server for open source image deployments

Credit for the below should go to the Spiceworks user who posted this on the Spiceworks forum some while ago. Its a great guide and I always turn back to it when setting up a Fog server.

Fog is an open source imaging solution which can be installed on top of many linux distros. For ease of use I usually put it on Ubuntu: I have had success using version 11.10 and newer versions of Fog will no doubt work with updated distros.

Install Ubuntu

I Wanted a GUI so I went with the desktop Ubuntu, you may want to go with Ubuntu server. So go to their website, download the workstation x86 ISO and burn it.

Install Ubuntu

Note that I installed it onto a rather ancient Dell D620 laptop (32 bit, max 4Gb memory) and used that for over 2 years with no issues. This is not something that needs high powered hardware.

1. English
2. Install Ubuntu
3. English
4. Select your Time Zone
5. Suggested Option
6. Use Entire Disk
7. Enter User Information and Computer information, I named mine 'foghat' with foguser
8. Install
9. Restart
10. Login

Install FOG

Video: http://www.youtube.com/watch?v=fvltHkAtW2A&fmt=18

1. Open Firefox
2. Go to http://www.fogproject.org and download FOG.
3. Open Terminal Applications->Accessories->

Terminal
4. cd Desktop (Remember Linux is case sensitive)
5. tar -xvzf fog*
6. cd fog*
7. cd bin
8. sudo ./installfog.sh
9. Select opt 2 Enter
10. N Enter
11. Default IP Enter
12. You dont need to set up a router IP but I will in case I ever use the server for DHCP.
13. Set up a DNS IP, just accept the default.
14. No do not change the default network interface.(you may not get this prompt if you have 1 nic)
15. I will not be using FOG for DHCP. (will require changing my current DHCP server.)
16. Note your IP settings and continue.
17. Enter to Acknowledge.
18. (I like to notify the FOG group, they have made a great product and deserve my feedback, choice is yours here)
19. gksu gedit /var/www/fog/commons/config.php and put your mysql password you typed during install in "MYSQL_PASSWORD", "" save and close. It has been noted that you also should change the MYSQL password here while you are at it /opt/fog/service/etc/config.php.
20. Browse to http://localhost/fog/management
21. Click install!
22. Click to log in. You can now reach this webpage from anywhere on the network where your server is installed by using it's ip address. eg http://192.168.0.100/fog/management I would reccomend putting an A record in your DNS called FOGSERVER this will make things easier to remember.
default: fog/password

Set up DHCP (For Windows DHCP)

1. Log onto your Windows DHCP server
2. Open DHCP console.
3. Right Click Scope Options -> Configure Options
4. Scroll Down to number 66 check and give the hostname of FOGSERVER
5. Scroll down to number 67 check and give the value pxelinux.0
6. Apply and close.

Install FOG service on client (Host)

Video: http://freeghost.sourceforge.net/videotutorials/FogServiceInstall.swf.html

1. Log onto the PC
2. Browse to http://FOGSERVER/fog/client
3. Click to download
4. Open
5. Run Setup.exe in the Fogservice folder
6. Accept defaults (FOG does not like to be installed in locations other than default)
7. Enter the ip or preferrably the hostname if you created one. FOGSERVER
8. Save Changes, Done, Close.
9. Open services Start->Run->services.msc
10. Scroll down and start "Fog Service"
11. This would also be a good time to make sure that PXE is your primary boot option in BIOS, you might need to enable it.

Create an image file.

1. Click on Image management.
2. New Image
3. Give it a name, description, default storage group, filename, and Image type (choose wisely). For dell computers with a utility partition you will HAVE to select multiple partition single disk.
4. Add.

Assign Image to Host

Assign the Image to a host, this will be the image the host uses to restore and deploy from, You can assign this image to as many PCs as you want. Useful for group Deployment.

1. Click on Host management.
2. List all hosts.
3. Click Edit next to your machine.
4. In Host Image select the proper image that you created in the previous step from the dropdown.

Upload an image.

Video: http://www.youtube.com/watch?v=jPPZr0abVfg&fmt=18

1. From another machine log onto http://FOGSERVER/fog/management login with fog/password
2. Click on Tasks (The Star)
3. List all Hosts
4. Click Upload next to the PC.
5. Upload image.
6. Click on active Tasks, and either wait for the PC to check in and autoreboot or Reboot it manually.

Test Restore/Deploy

1. Click on Tasks (The Star)
2. Click Deploy next to your PC.
3. Click image All computers.
4. Verify image by booting computer and making sure everything works.

Conclusion

This is more than worth the effort. Make sure you have enough storage for your images. This tutorial should have gotten you to the point where you can start to play with FOG yourself even if you have absolutely NO idea how to run Linux.
From here you can start creating groups to image, advanced tasks and start shaping things to your environment.

Change the kernel that Fog clients use for PXE boot

noreply@blogger.com (Phil Mulley) — Sat, 23 Mar 2013 21:13:00 +0000

Change the kernel that Fog clients use for PXE boot

We recently tried to use FOG to image a Dell Latitude E6510, and had problems due to the kernel that FOG was pushing to it. The kernel didn't support the Intel 82577LM Gigabit NIC. Here are the steps I
took to change the kernel to one that supported the NIC.

Download the kernel you want to use

Log into the FOG web management interface. Click on the about icon.
Click on Kernel Updates on the left side. The page will list all of the available kernels that FOG has compiled. For me, the Kernel -2.6.37 Core worked for us, and is the most up-to-date kernel they offered (there will be new ones on there now!.
Click on the kernel you would like to download, and name the kernel something other than bzImage, in case something goes wrong. We used Feb11bzImage for the name. Click the next button.

Configure TFTP Server in web interface

While still logged into the web management interface, click on the about icon, and click on the FOG Settings button on the left side.
Scroll down to TFTP Server section. Change the entry for FOG_TFTP_PXE_KERNEL to read fog/kernel/kernelname, where kernelname is the name you gave to the kernel you downloaded (Feb11bzImage for me).
Click Save Changes.

Configure FOG Server

Log into the fog server. The default credentials are username:root and password:password. When presented with the FOG Server (unless you have changed the defaults, and obviously you should change them from these)
Configuration Menu, type q for quit, press enter.
Type: cd /tftpboot/pxelinux.cfg/
This changes the current directory
Type: cp default default.old
This creates a copy of the default file, in case something goes wrong when changing it.
Type: vim default
This opens the default file with the vim editor (replace the command "vim" with the one for an alternative editor if you prefer: ie gedit)
Everywhere in the file where the line: kernel fog/kernel/bzImage appears, change it to: kernel fog/kernel/kernelname
After you are done editing the file, press escape, press the colon key, and type: wq!

Restart FOG Server

Restart the FOG server.

Test imaging

Try imaging a client with the new kernel.

Conclusion

These are the steps I took to get FOG 0.29 to successfully image our Dell Latitude E6510 machines. From what I have read, updating the kernel is usually a good idea solely for support of new hardware, and updated drivers. If anything goes wrong, you should be able to deletethe default file, and rename the default.old file, and change the one entry in the web interface to roll back to the old kernel.
