Ubuntu 9.04 UXA Graphics Acceleration

Posted on 21:00 by Unknown

When I switched on my Karmic development laptop the X server reverted back to low-res. Guess its time to start UXA testing. Right now UXA is very unstable and presents strange problem like this one. The fonts are totally messed up in Firefox, Openoffice.org and gedit. Any ideas what might be the problem?

Update: 25 May, 2009 Found that this problem is triggered when I restart the computer from hibernation.

Linux Wx Notation Phonetic Keyboard layout for Devangari (Hindi)

Posted on 08:07 by Unknown

Few hours ago WX notation phonetic keyboard layout for Devnagari(Hindi) has been included into Ubuntu. This closes the ubuntu #274024 and freedesktop-bugs #19753 reported last year. This is a great news for the Wx keyboard users, they can now have this keyboard layout by default in gnu/Linux.

While at University of Hyderabad I had copy the symbols file for the keyboard layout every time a new gnu/Linux system was installed. Its wonderful to see a solution developed for use inside our lab has been contributed back to the gnu/Linux community worldwide.

X11::GUITest Build Errors

Posted on 00:53 by Unknown

X11::GUITest and X11::GUITest::record CPAN modules help you control X11 applications using perl programming language and do some rather simple automation tasks.

But building these modules can be a pain, if don't know about the right dependencies like libxt-dev and libxtst-dev .

Start X Painlessly

Posted on 02:45 by Unknown

Perhaps I should start this post in V. S. Naipaul style with a dedication 'To Sajith for asking me why' ;). Watching over my shoulder while I was working on my laptop, he asking me why I used this particular command to start the X Window server.

$ openvt startx

As command line junkie I work on linux console most of the time, only starting graphical X server with startx command when needed. The problem with using startx command is that it locks up the terminal by printing numerous warnings and messages while the X server starts and thus making the terminal unusable. Also I limit the number of virtual terminal on my computer to just two instead of standard six on gnu/Linux operation system.

So, the openvt command provided by the console-tools package helps me spawn a new virtual terminal and that's where all the warning and messages are printed leaving me to continue working in peace. Another added advantage to this is that I can do startx from a Emacs shell instance too, this is neat!.

Ubuntu is running in low-graphics mode

Posted on 07:01 by Unknown

I haven't figured out what went wrong, must be a bug or my disk started to show its age. After couple of reboots and doing file system check everything went back to normal. The issue seems to be that half of modules went missing, Beats me!

Unkown i810 Display Problem

Posted on 05:42 by Unknown

When shutdown is initiated from a X window session my old HP Pavilion desktop turns green and barfs all over me. If you know a fix, shout it out.

Update: Mis-spelled word "Unkown" in the title of this post, leaving it uncorrected since it will mess up the url of the post.
