Enable wakeup from suspend with usb keyboard or mouse in Linux Ubuntu

2011-09-05T14:49:00.001+02:00

This guide is exactly what you need :)

In short;
1.) Enable it in your bios
2.) echo DEVNAME > /proc/acpi/wakeup
3.) Correct DEVNAME is found using the following script:

grep "USB.*pci" /proc/acpi/wakeup | cut -d ':' -f 2- | while read aaa; do find /dev/.udev -name "*$aaa*" -print -exec grep "$aaa" /proc/acpi/wakeup \; -exec echo \; ; done

4.) Add cmd(2.)) to /etc/init.d/wakeup

Your wakeup file should look something like this:

#!/bin/sh

# Set /proc/acpi/wakeup to allow devices to wake system

# sudo sh -c "echo USBX > /proc/acpi/wakeup"

echo USB4 > /proc/acpi/wakeup

5.) Enable wakeup to boot at startup:
update-rc.d wakeup defaults
6.) Done...

Saved radio presets disappears on car stereo

2011-08-01T16:57:00.002+02:00

Solution: You have probably just installed your car stereo wrong. Take a look at the wiring where you will have one red and one yellow cable. It should be possible to switch these around. Do that, and it should work.

Happened and solved with my Pioneer car stereo..

Mediakeys for spotify in Linux

2011-06-29T02:30:00.000+02:00

There is two ways of doing this.

1.) Native Spotify player for Linux (requires Unlimited or Premium)
Create spotify-control containing this (credits go to this allenap):

#!/usr/bin/env python

import dbus
import sys

if __name__ == '__main__':
    session = dbus.SessionBus.get_session()
    spotify = session.get_object(
        "org.mpris.MediaPlayer2.spotify",
        "/org/mpris/MediaPlayer2")
    for command in sys.argv[1:]:
        getattr(spotify, command)()

su
chmod 755 spotify-control

Next, put the file into i.e. /usr/bin/
Now you got a cmd way of controling your spotify player.. spotify-control Previous, spotify-control Next and spotify-control PlayPause...

If you are using fluxbox as I am, add the following to your ~/.fluxbox/keys

# Spotify
Mod4 Right :Exec $(spotify-control Next)
Mod4 Left :Exec $(spotify-control Previous)
Mod4 space :Exec $(spotify-control PlayPause)

Save, "reconfigure" (or restart fluxbox), and you are done..

Now you can use your windows button + Right/Left for Next/Previous or Space to pause :)

2.) If you are using spotify via wine..
This way is a bit more "unslick" and nasty.. But it works..
You do it the same way, except you use the following script located here..

Add temperature to conky

2011-06-18T19:22:00.000+02:00

After some recent debian updates, the proc files which conky got it's temperatures from disappeared. I found a way though to work around this, and get the temp into conky.

1.) First, open your console.
2.) Type acpi -t. This way you will see which sensors you can grab the temperatures from. You will get an output looking something like this:
Thermal 0: ok, 55.0 degrees C
Thermal 1: ok, 35.4 degrees C
Thermal 2: ok, 50.0 degrees C
Thermal 3: ok, 58.0 degrees C
Thermal 4: active, 60.0 degrees C
3.) Decide which thermal sensor you want the temperature from. In my case I found out the cpu was "Thermal 3". Now we are gonna sort out this line.
4.) Type: acpi -t | grep "Thermal 3". You should now get only the Thermal 3 line. So far so good. Now we need to sort out only the temperature, using "cut".
5.) Type: acpi -t | grep "Thermal 3" | cut -c16-19. The -c- might be different from you. Adjust it so you now get an output displaying ONLY the temperature.
6.) When you've made the correct command line, add it to your conkyrc like this:

${execi 1 acpi -t | grep "Thermal 3" | cut -c16-19}C

Laptop running warm and noisy fans

2011-06-18T18:56:00.000+02:00

After some years of use my laptop started getting really warm when the work load increased. As a result of the heat, the fans also started making a lot of noise. This problem did not exist when I got it, or the first years..

The cause was pretty obvious. Dust and dirt had piled up inside my laptop, and especially on the fan(s). My laptop only have 1 fan, so I went straight for it. Following the service manual for my computer (hp nx7400) I removed the keyboard, and the fan came to sight.

Next I got the vacuum cleaner. Yep, that's right, the good ol' vacuum cleaner. It might be an idea to add a thinner tip on it while doing this. I didn't though. Next, the clue is to hold the fan so it wont spin when vacuum cleaning it. If you dont the fan might ending up spinning backwards, which could break it. While holding the fan, clean it thoroughly until it's dust free.. Next clean any heatsinks and other visible dust.

Now reassemble, and hopefully it should not run warm that easy, and the fans shouldn't spin up all the time! At least it worked great for me!

Import old GED 5.0 file from family tree maker to new version

2011-05-02T20:25:00.000+02:00

This is a quick hotfix for this. If you exported your old family tree maker file to a GED file version 5.0, you can't open it again in newer versions. But it's actually saved in 5.3, which is pretty similar to 5.5. Simply open the GED file in notepad, find the line which specifies the version (5.3), rename it to 5.5, save, and open it in family tree maker 2011 or whatever you are running ;)

PS... Scrapbook elements gets lost in the GED format..

Remove whitelist in NX7400 bios

2011-05-02T20:22:00.000+02:00

Yes, it's possible! As well as you will get SLIC tables. This should remove any 104 or 105 errors on NX7400. There is also available bioses for other HP models for this...

First of all, I take no responsibility in case you brick/ruin your bios :P

Now to it...
1.) Download this toolkit to make a bootable USB key with rompaq which is the flashing tool. Follow the readme, and everything will start automaticly when booting up... http://www.sendspace.com/file/rip4sc
2.) Boot up with this, make a backup of your current bios. If you have a nx7400 you will get a file named: 68YGU.BAK
3.) Download your new bios from here (NX7300/NX7400).
4.) Open the file, and extract the .bin file to the usb key, and rename it to 68YGU.BIN.
5.) Reboot, and chose to upgrade bios.
6.) You are done :-)

For more info, and complete list of bios'es available check here.

Solution: Flash drive identified as SDA during ubuntu install

2011-04-01T17:35:00.000+02:00

Problem: My Gigabyte motherboard identified my USB Flash Drive as SDA, so it swapped place with my drive which appeared as SDB during install.

This is only a problem when it comes to the MBR installation, which will be installed to sda, nomather if you chose to install your system to sdb.

Fix?
Boot your system again, but remember to keep your usb drive inside the first time you boot. Then simply run this cmd:

sudo grub-install /dev/sda

Just make sure your linux drive this time is identified as sda :)

Cheap SD cards for ipad 2

2011-01-17T03:11:00.000+01:00

As we know the iPad 2 will be equipped with SD card slots. This enables you to easily view photos, video and listen to music from devices such as digital cameras, digital video recorders and others.

Navigating through what card you should buy isn't always the easiest task as there is multiple types of cards, speed-classifications and especially great price-gaps. Knowing where to buy these cards for the best price available is a huge advantage. I will tell you my tips on where to get these cards the cheapest way.

My favourite places for buying these cards is:
1.) MyMemory.co.uk - Greate prices and thrusted shop to buy from.
2.) Dealextreme.com - Great prices, but not so easy to navigate and not so many sorts of cards available.
3.) Ebay.com - Great prices, but you can't always thrust the sellers.

Solution: How to enable iphone personal hotspot?

2011-01-14T15:53:00.000+01:00

This is a new feature which came with iOS 4.3. First make sure you got this version or newer. Enabling the feature isn't that hard actually, and it enables you to share your internet connection on a wireless connection (wifi) so others can use your phones internet connection.

Just go to your phones home screen, go to settings, and then select "Personal Hotspot". Tap "Wi-Fi password" and set a good password, next tap the "Personal Hotspot" switch to enable it, and you are done.

Now there will appear a new Wireless Network which you can connect to on other devices and you got an internet connection.

Cheap wireless whdi graphics card?

2011-01-14T15:45:00.000+01:00

The first wireless graphics card has finally been released. It's called GeForce GTX460 WHDI 1024MB PCIe 2.0 and can transfer video to WHDI enabled devices. It can in this way stream uncompressed 1080p video to devices which support WHDI.

What the price will be we dont know yet, but I guess the price will be high at first, but lets hope it decreases to an affordable level on a later stage.

You can read more about it here.

How to multitouch on iPad

2011-01-14T15:40:00.000+01:00

Here is a quick video to demonstrate how to multitouch on the iPad, a feature which came with iOS 4.3. You can use four or five fingers to pinch to the home screen, swipe up to reveal multitasking bar or swipe left or right between apps..

Fix: This accessory is not optimized for this iphone

2011-01-11T00:04:00.000+01:00

Ok, this problem usually comes from either dust in the ports (docking or audio port) or water damage. In my case it was dust in the docking port, which easily got fixed!

PS! Do this on your own risk :-) I don't take any responsibility for you ruining your phone :-)

How to fix:
Dust in port: Turn off the phone and use a DRY toothbrush, and clean out the dirt.

Water: This one is harder, and might not work if this is the case. Turn the phone off, and try to dry it either by putting it in a bag of rice to dry it out, use a hairdryer or/and put it on some warm place to dry the moisture.

Canada Goose Chilliwack Measurements

2010-10-16T17:03:00.001+02:00

Here is the measurements for the Canada Goose Chilliwack jacket. Got this from a friend. If there's some sort of copyright on this, please comment, and I will get back to you.

Chilliwack Measurements (in inches*)
SIZE	3XS	2XS	XS	S	M	L	XL	2XL	3XL
CHEST – 1”below armhole (1/2)	21	22	23	24 1/2	25 1/2	27 1/2	29 1/2	31 1/2	33 1/2
SWEEP – jacket closed (1/2)	12	13 1/2	15	16 1/2	18	19 1/2	21	22 1/2	24
SLEEVE LENGTH – from center back	34	34 3/4	35 1/2	36 1/4	37	37 3/4	38 1/4	38 3/4	39 3/8
SLEEVE LENGTH UNDERARM	18.5	19	19.5	20	21	21.5	22	22.5	23
SLEEVE WIDTH @ BICEPS (1/2)	9 1/4	9 1/2	9 3/4	10	10 3/8	10 3/4	11 1/8	11 1/2	12
SLEEVE WIDTH @ HEM (1/2)	3	3	3 1/4	3 1/4	3 1/2	3 1/2	3 3/4	3 3/4	3.3/4

To convert to cm, multiply by 2.54

Some tips!!!
The jackets may seem sized small because of their short length. But they are supposed to be short. That means; be careful with picking bigger sizes because the arms length and chest size might get to big.

I wear one for casual use.. Meaning often just a shirt or a thin sweather underneath, so heres my tips:
If you are 190cm+ tall and a bit of shoulder width/chest size: You can probably go for an XL.

If you are lower then 190cm, do not even think of picking an XL.

FIX: Can't click flash videos in firefox.

2010-07-23T00:59:00.002+02:00

This bug has been fixed in Firefox v. 3.6.7. Upgrade to this version.

If you are running i.e. debian squeeze as I am, simply add swiftfox(google it) to your apt sources & install it.

Java in Debian Squeeze not appearing

2010-07-03T22:41:00.000+02:00

Had lots of problems with Java not "appearing" or seems to not be loading (though it does) in Debian. Using the sun java6 plugin.

Here's my howto for Debian Squeeze + Java + (Swiftfox/iceweasel/google chrome)

1.) Install sun-java6-plugin (apt-get install sun-java6-plugin)
2.) Make sure your browser has loaded the java6 plugin. In the browser of your choice, type: about:config and check that java6 is loaded. If it's not, google :P Shouldn't be hard to find. If not, I can write a howto on it.
3.) Go here and test your java. If you get an error, click the box, and read the first lines. Otherwise, you're done.
4.) If the error looks like this:
java.net.ConnectException: Network is unreachable
then edit the following file: /etc/sysctl.d/bindv6only.conf, and make sure net.ipv6.bindv6only is set to "0". Save and quit.
5.) Restart procps like this (as root): invoke-rc.d procps restart
6.) You're done, and it should be working.

Bluetooth and Thunar

2010-07-01T23:40:00.000+02:00

This is a copy paste from a forum. Storing it here in case it should disappear, and this is the "golden ticket" to bluetooth browing in fluxbox :) Remember to change dolphin to browser of choice. For example thunar.

SOURCE: http://blueman-project.org/forum/viewtopic.php?f=7&t=80&sid=48f91d78e39e09341f63507c1036d22f&start=10

Hi,

first, thanks a lot for the useful pointer on how to use something different than nautilus for blueman's "Browse Device".

It works well, but nevertheless, there are a few shortcomings:

BT channel 10 is only correct for some devices (mainly Nokia S40, it seems).

There is no explicit removal of the obex mount and its mount point.

Only one device can be browsed at once.

The following script gets rid of these issues. I have tested it successfully with more than one devices (2, actually) on Debian Squeeze with KDE4 and dolphin. Every other file manager will work just as well, you only need to change the dolphin invocation appropriately.

Usage
The first click on "Browse Device" will setup the obexfs mount point (as .obex- in your home directory) and open dolphin with it. The second click on "Browse Device" will disable the obex mount and also remove the mount point again. Blueman's connection graph will help to indicate the state you are currently in.

Requirements
You will (at least) need the packages blueman, obexfs, fuse-utils from your favorite distribution. You may need a new session start to make sure you are a member of the fuse group. Additionally, the script (as it is) expects a writable logfile, which you may create as root with:

Code: Select all

touch /var/log/blueman-browse-helper.log chmod a+rw /var/log/blueman-browse-helper.log
Now, enter

Code: Select all

blueman-browse-helper %d
in the field Command to start an obex ftp browser in the Advanced section of Local Services... (after right-click on tray icon) and save the following script accordingly as (e.g.) /usr/local/bin/blueman-browse-helper (as root, of course, and make it executable for users).

Now, finally, here comes the script:

Code:

#!/bin/bash log=/var/log/blueman-browse-helper.log mp=~/.obex-"$1" channel=`sdptool search --bdaddr "$1" FTP | awk '/Channel:/ {print $2}'` if [ -e "$mp" ]; then echo "`date`: cleaning up mount point '$mp'" >> $log fusermount -u -z "$mp" &>> $log rmdir "$mp" &>> $log else echo "`date`: opening FTP channel '$channel' for mount point '$mp'" >> $log mkdir "$mp" &>> $log obexfs -b "$1" -B $channel "$mp" &>> $log dolphin "$mp" &>> $log fi echo "`date`: `basename $0` finished for mount point '$mp'" >> $log

Have fun,
musial

Change default file manager for kde

2010-06-29T00:28:00.001+02:00

You can also do this in a GUI via kcontrol, but I am originally running gnome with fluxbox so I had to find out another way to do this, since it affects several apps like ktorrent and transmissions actions when chosing to open a folder via them.

It was actually pretty easy:
1.) Open a terminal and edit your ~/.local/share/applications/mimeapps.list
2.) Go to /usr/share/applications and check out what your filemanagers folder handler file is called. E.g. thunars is Thunar-folder-handler.desktop, which I will use (case sensitive).
3.) In the mimeapps.list you opened, edit or add the following line:
inode/directory=(your-file-handler);
Example:
inode/directory=Thunar-folder-handler.desktop;

Save, and relogin to your session ;) It shall now work!

PS1: The file mimeapps.list may not exist. If it doesn't create it. I had to do that one.
PS2: You can also try to edit defaults.list if located in the same directory and add the line there.

Upgrade Wifi Card on HP NX7400

2010-06-13T18:45:00.001+02:00

UPDATE [2.5.2011]!!!
Solution is now available for this right here!

Old post:
Recently tried to upgrade the 54mbit (abg) wifi card on my HP NX7400 laptop to the 802.11n standard. I'm sorry to inform you that this simply is NOT possible at the moment, unless someone manages to create a hacked bios. The problem is a whitelist in the bios containing which WIFI cards to accept. Only original cards are located in this, so no luck when trying to upgrade it.

What happens is you boot up and get a 104 error telling you to replace the mini pci wifi card.

If someone anyhow DO have a way to do this, PLEASE inform me/us here in the comments ;) The only way I know right now though is to use a USB or PCMCIA USB card.

nx7400 audio in Windows 7

2010-06-02T18:09:00.000+02:00

Had some problems trying to locate drivers for my audio device on the HP NX7400 in Windows 7. Problem was Windows 7 couldn't locate the integrated speakers, and I only got a red sign on my audio device in my lower right corner.

The solutions:
Go to hp.com, find the driver package for NX7400s audio device for Windows Vista and install it. Works like a charm! :)

Cliffs:
Windows Vista audio drivers for NX7400 works GREAT for Windows 7 on NX7400.

Hope this helps someone else out :p

Nikon Standard Lense Upgrade

2010-05-12T18:22:00.000+02:00

My Nikon AF-S DX Zoom-Nikkor 18-55mm f/3,5-5,6G II standard lense on my Nikon D90 broke recently so in stead of getting a new one, I spent a bit more for a slightly better one. I bought a Sigma 18-50mm F/2.8-4.5 DC OS HSM.

Having used the lens for my weekend vacation I have to say that I'm very satisfied with it. The extra aperture it brings (3.5 to 2.8) really helps, and the quality of my photos seems to be of higher quality as well.
