Linux is comming

Linux is an open source program. This means that users are able to customize the code in order to suit their needs, so that the program can be as convenient for everyone to use as possible. Windows does not offer such a luxury and this is a major disadvantage in such a system. Also, Linux is very reliable. If you are playing an exciting game of Partypoker and do not want to be interrupted, then the last thing you need is to have to reboot. Thankfully this happens very infrequently with Linux when compared with other programs.

While Windows is frequently targeted by spyware, Linux is very secure and has managed to remain so. It is also faster than other operating systems which should prove to be very convenient for its users. One of the main things that users like about Linux is that they have such control over the program. The operating system is effectively in the hands of the users, who can alter the desktop look and features to suite their own needs. It looks as though people are catching on to these advantages and that the coming year will be a successful one for Linux.

sudo passwd

After that you are asked to type in the new root password twice. Finally, your root user has its own password.

After a softwares that is installed from PPA, you can remove it if you don’t feel it works as you want, you can remove it then remove their PPAs. It’s remove very easily with one or some softwares, but it’s problem when you want remove a lots of  softwares from some PPAs. This problem can be solve by experienced users or you can make a batch command like experienced users with PPA-Purge. Ironically, the ppa-purge package itself is available on a PPA. How strange is that?

What is PPA-Purge

PPA-Purge will reset all packages from a PPA to the standard versions released for your distribution. So basically its like a way to restore your system back to the way it was before you installed packages from a PPAs.

How to use PPA-Purge

1. Install PPA-Purge from Ubuntu Repositories ) (it has been added to the official Ubuntu repositories since version 10.10 Maverick Meerkat) by Terminal:

   sudo apt-get install ppa-purge

2. To use PPA Purge for any Ubuntu derivative, use the following command:

   sudo ppa-purge -d  ppa:

   or it’s simpler with Ubuntu 10.10 and later:

   sudo ppa-purge ppa:/

Let’s try by yourself!

So, I recommend pSX as Playstation One Emulator on Ubuntu x86/amd64. Let’s install it then play your favorite PSX games.

• pSX requires OpenGL library and gtkGLext to work. Make sure it’s installed. The package lib32gtkglext1_1.2.0-3.2-amd64.deb must be installed for 64bit/amd64 systems. This is not needed for 32bit systems.
• pSX requires having a playstation bios file to run. I can’t legally supply you with one, so just Google it with scph1001.bin keyword.
• While running, due to a conflict with pSX and Pulseaudio, Pulseaudio is disabled while running pSX. This may make any program using it crash and will probably make the mixer/sound volume control unavailable while pSX is running. It should return to normal when pSX is closed. If not, close any program currently using sound. Sometimes, I need restart my  laptop because it’s not works.

How to play a PSX game:

• Download pSX and then extract to your home folder.
• Get scph1001.bin, move it into bios folder of pSX
• Move or copy Playstation One game images into cdimages of pSX, cd images will be run smoother than original disk
• Run pSX then config controler if you want.

At this time, I’ve tried ePSXe and PCSX for Linux but it’s crash during testing time on Ubuntu 11.4 64bit, so I’ll write about these in next time.

XBMC

• Add Stable XBMC Team PPA in to Ubuntu Repository with

  sudo add-apt-repository ppa:team-xbmc

• Don’t update Ubuntu sources list, you will get errors and can’t install xbmc, just go to Update Manager > Settings > Other Software then edit ppa:team-xbmc from natty to maverick because the current PPA of XBMC Team not has natty packages.
• Update the Ubuntu Repositories then install XBMC

  sudo apt-get update && sudo apt-get install xbmc

You can install XBMC on Ubuntu 11.04 too with Unstable of XMBC Team ppa:team-xbmc/unstable, but I’m not recommend you to do this, it’s has a lot of errors.
You can install another softwares like XBMC (in this time) on newest Ubuntu version.

Mozilla Thunderbird 5

Mozilla decided to bump up the version of Mozilla Thunderbird to 5.0 from 3.1. Such a upgrade was meant to bring Thunderbird in line with the development status of Firefox, which has now reached version 5. Mozilla Thunderbird 5 promises to be a faster, more efficient and feature rich email client than its predecessor.
The latest version of Thunderbird has the following changes:

• More responsive and faster to start up and use
• Thunderbird is based on the new Mozilla Gecko 5 engine
• New Add-ons Manager
• Revised account creation wizard to improve email setup
• New Troubleshooting Information page
• Tabs can now be reordered and dragged to different windows
• Attachment sizes now displayed along with attachments
• Plugins can now be loaded in RSS feeds by default
• There are several theme fixes for Windows Vista and Windows 7
• Support for Mac 32/64 bit Universal builds (Thunderbird no longer supports PowerPC on Mac)
• Over 390 platform fixes that improve speed, performance, stability and security

With the streamlining of the release cycle with the Firefox browser come additional similarities. Thunderbird now sports the very same add-on manager that Mozilla added to the Firefox browser earlier. The big version jump from Thunderbird 3.1 to 5 will definitely render some addons incompatible, but it’s not a big problem, let’s wait!
The new version has not been publicly announced yet on the official Mozilla website, and Thunderbird users who are already running the program will not receive update notifications at this point in time.
On Ubuntu, you can install or upgrade to the latest version of ThunderBird by using ThunderBird Stable PPA

sudo apt-add-repository ppa:mozillateam/thunderbird-stable
sudo apt-get update
sudo apt-get install thunderbird

Try it now!

• Install b43-fwcutter package may be fixed this issue because the default installation of Ubuntu not make this package installed by default.
• Restart your laptop then try to connect again, if not work then follow next step below.

Step 2:

• Install bcmwl-kernel-source package then reboot your laptop.
• Once you connecting to the internet through wired connection, open a terminal & type:

  sudo apt-get update && sudo apt-get –reinstall install bcmwl-kernel-source

• That’s it, just reboot your system. after a reboot, you can see driver installed and working.

If not works again? Hmm.. try to find or ask on Ubuntu Forum because it’s not occured with me before. Hope this fix will be work with you.

Disable Ubuntu services autostart

Traditionally, Ubuntu provided various tools to manage services. There are various methods for managing access to system services:

• /etc/init.d/service
• rcconf
• update-rc.d
• etc…

You can install third party softwares to manage Ubuntu services as you want, just as BootUp Manager (bum), rcconf… But in this topi, I’ll tell you the way to prevent automatic run a services in Ubuntu with simple and powerful command:

sudo update-rc.d -f service-names remove

• service-names: name of the service which will be disable, just as mysql, apache2….
• -f option: force disable services
• remove: disable command

If you want to enable a service automatic running, you can use the command below

sudo update-rc.d service-names defaults

Do as your self!

1. Ubuntu 11.04 – Natty
2. Ubuntu 10.10 – Maverick
3. Ubuntu 10.04 – Lucid

Using Package Repository

The Canon CAPT printer driver is split into two packages: cndrvcups-capt and cndrvcups-common available from the Canon printer driver PPA. As of May 2011, this PPA contains 2.20 version of the Canon drivers, build for i386 and amd64 on Lucid, Maverick and Natty. This is the easiest way to install the drivers.

To add the PPA to your system and install the packages do:

sudo add-apt-repository ppa:michael-gruz/canon
sudo apt-get update
sudo apt-get install cndrvcups-capt cndrvcups-common

Install without using the package repository

Using the prebuilt packages from the package repository is the easiest way to install the Canon drivers. If for some reason you prefer to use the older install method that does not utilise a package repository, read the following instructions.
Download Official Canon Printer Driver then choose the right install package.
Unfortunately, they’re not designed for Ubuntu and they are compiled to work only on a 32bit OS. Therefore the only solution for the one is to compile their own drivers using Canon’s sources, but not following Canon’s instructions.
An alternative and more hassle-free solution would be to use an automated BASH script that handles all the installing procedures and works both on 32-bit and 64-bit systems (while the guide mentioned before is useful only for people with 32-bit machines & Ubuntu 10.10). The archive containing the script is located here.
The current supported printer models for the 1.90 release of the driver are: LBP-1120, LBP-1210, LBP2900, LBP3000, LBP3010, LBP3018, LBP3050, LBP3100, LBP3108, LBP3150, LBP3200, LBP3210, LBP3250, LBP3300, LBP3310, LBP3500, LBP5000, LBP5050, LBP5100, LBP5300, LBP7200C.
Running the script is pretty easy:

sudo ./canonLBP_install.sh PRINTER_MODEL

where PRINTER_MODEL is one from the above. Any other printer model you would try to use will give you an error message and the script will exit.
Make sure you have ESP Ghostscript and OpenPrinting Driver Interface installed on your system. If you are not sure, type following command into a terminal:

% gs -h | grep opvp

this should output:

lj5mono ljet2p ljet3 ljet3d ljet4 ljet4d ljetplus nullpage opvp oprp pbm

if you don’t get the correct line the OpenPrinting Driver Interface is not installed and you should install it before you proceed.
To install the ESP Ghostscript which has the OpenPrinting Driver Interface, first, be an administrator, and open the file “/etc/apt/sources.list” of your system, and add the list by following two lines, and save the file.

deb http://kmuto.jp/debian/mtu debian_dic main contrib non-free
deb http://ftp.jp.debian.org/debian stable main contrib non-free

Next, install the new ESP Ghostscript by the following command.

$ sudo apt-get update
$ sudo apt-get install gs-esp

Adding a printer

Go to System->Administration->Printing add printer. Choose “Add printer“. Do not choose USB Printer found by Ubuntu here. Select “CAPT Printer”. You should see “ccp” in URI. Change it so URI should become “ccp:/var/ccpd/fifo0″. Click “next”, find your model and add your printer. Choose English variant if you see Japanese and English variants. Also If you do not have you exact model in list, choose nearest. For example, for LBP 810, I choose “LBP 1120″.
To view your Canon printer information, type this command below into Terminal:

$ sudo ccpdadmin

you will get:

Usage:
  ccpdadmin [-p Printer-name -o Printer-dev-path]
  ccpdadmin [-x Remove-Printer-name]

 CUPS_ConfigPath = /etc/cups/
 LOG Path        = None
 UI Port         = 59787

 Entry Num  : Spooler   : Backend       : FIFO path             : Device Path   : Status
 ----------------------------------------------------------------------------
     [0]    : LBP810    : ccp           : /var/ccpd/fifo0       : /dev/usb/lp0  :

Now it is time to restart the system. If all goes well the system should restart and at the login page be able to print. This guide will not cover setting up cups for network printing.

After you login open a terminal and run:

sudo /etc/init.d/ccpd status
Canon Printer Daemon for CUPS: ccpd: 1135 1131

This shows the process Id’s for the two ccpd processes that should now be running. If you only see one then you still have a problem with the way the ccpd daemon is starting. Please check carefully you have completed all the steps above.

At this point you should be able to print a test page all being well.

If you run into problems try turning your printer off, restart your computer and only turn your printer on, after you have logged in.

Install Adobe AIR in Ubuntu

Have you ever tried to install Adobe Air in Ubuntu. I’ve installed Ubuntu 11.4 64bit and I find 64-bit binaries of AIR are not currently available. Right now Adobe AIR is only officially available for 32-bit Linux.
Installing Adobe AIR 64-bit on Ubuntu can be quite tricky if you’re not quite familiar with the commands and if you’re new to Linux/Ubuntu. So for the sake of those users, I’m sharing this short step-by-step tutorial on how to install Adobe AIR 64-bit on Ubuntu.

1. Download the Adobe AIR installer – http://get.adobe.com/air/
2. In a terminal window go to the directory containing the adobeair.deb file then create adobe-air-x64 folder with command:

   mkdir adobe-air-x64

3. Extract the deb file to the adobe-air-x64 folder:

   dpkg-deb -x adobeair.deb adobe-air-x64

4. Extract the control files:

   dpkg-deb --control adobeair.deb adobe-air-x64/DEBIAN

5. Change the Architecture parameter from “i386″ to “all”:

   sed -i "s/i386/all/" adobe-air-x64/DEBIAN/control

6. Package the 64-bit deb file:

   dpkg -b adobe-air-x64 adobeair-all.deb

Now you can install Adobe AIR on a 64-bit system by running adobeair-all.deb file.
Note: Some AIR application not works correct in Adobe AIR 64-bit.
