How to disable Pidgin notification popup

Posted by erawat – 21/05/2010

Ubuntu 10.04 (Lucid Lynx) comes with EMPathy IM Client. However, I still prefer to use Pidgin for the my default IM client.

One default feature of Pidgin is a notification popup. It is always annoying me when I use it as you can see in a following picture.

nottify

The notification popup is always pop when new contact is online.

To disable this feature:
1. Click Tools and then click Plug-ins (or use Ctrl + U)
2. Tick Libenotify-popups plugin off as it shows below.

Then you will never see the notification popup any more.

Installing Java on Ubuntu 10.04

Posted by erawat – 20/05/2010

I wanted to install Java Development Kit (JDK) on Ubuntu. After installing Ubuntu on my laptop. Sun JDK/JRE didn’t come along with it so I typed “java” to see which package that I could use to install JDK in the system.

erawat@erawat-laptop:~$ java
The program 'java' can be found in the following packages:
 * gcj-4.4-jre-headless
 * openjdk-6-jre-headless
 * cacao
 * gij-4.3
 * jamvm
Try: sudo apt-get install

As the result above, the sun-java6 has been removed from the default repository and openjdk-6 is not stable. So, I have been searching how to install the sun-java6 on Lucid then I found out from Ubuntu 10.04 LTS Release Notes that

For Ubuntu 10.04 LTS, the sun-java6 packages have been dropped from the Multiverse section of the Ubuntu archive. It is recommended that you use openjdk-6 instead.

If you can not switch from the proprietary Sun JDK/JRE to OpenJDK, you can install sun-java6 packages from the Canonical Partner Repository. You can configure your system to use this repository via command-line:

It is simple to add third-party repository into the system.

sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"

Afterward, use a normal installation of sun-java6 to install the jdk on the system as following.

sudo apt-get install sun-java6-jdk sun-java6-jre

Finally, the JDK/JRE has already been installed and now I got Java on my system as the result below.

erawat@erawat-laptop:~$ java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)

Ubuntu 10.04 Lucid Lynx

Posted by erawat – 19/05/2010

I have moved from Windows 7 to Ubuntu 10.04 (Lucid Lynx) today and I had not used Ubuntu since I brought Macbook so, the lastest version of Ubuntu that I used is 9.04 (Jaunty).

The Macbook was spilled coffee on, and I decided to buy a laptop PC which is Acer. so, I’ve got free Windows 7 home premium which comes along with the laptop. It’s improving a lot from Windows XP and Vista.  After, I have been using Windows 7 for 6 months and Lucid came out, I’ve read many reviews they showed that Ubuntu has also been changed a lots in this version.

I have installed Lucid on the laptop and still keep Windows 7 and all hardware are working well such as web camera, microphone, wifi or even wireless mouse. I haven’t seen any problems since it has been used as well as my machine is Acer Aspire 5735Z (the UK version)

So, the list of basic programmes which I always installed these programme and something that I did after fresh installing on the system as you can see in a following:

Application:
Unrar – an essential application that allows user to unpack RAR file.
Skype – a popular voice and video chat, it’s also available on Linux.
VCL – the useful media player which enables user to play many types of media.
Sun-JDK – I’m java lover. (many Linux applications that I used or might use in the future are normally written in Java)
GIMP – GIMP is the GNU Image Manipulation Program. It is a freely distributed piece of software for such tasks as photo retouching, image composition and image authoring. (http://www.gimp.org/) – I’m not graphic people so, the application is rarely used by me.
Compiz-plugin – an application that provides some effect for Ubuntu.

A part of mentioned applications above, Ubuntu provides enough essential applications for basic user to use it. It’s perfectly free open source operating system.

Task:
Changed front size of system from 10px, which is default size, to 9px. (the screen seems to be bigger).
Added Thai Keyboard and set key to change keyboard’s layout to ALT + Shift

The basic instruction of using and installing applications on Ubuntu can be queried at Ubuntuguide.org

The my system schootshot, it look clean and simple.
