Trouble with “/etc/X11/xorg.conf”

Heya… It’s been a long long time since my last post in here. I’m sorry, I went totally haywire from the Linux world… Only Academics and all that Master’s Degree plans…

Well, Since 2 weeks, I’m back with my Linux box tweaks. Tonight, At very early hours, I was trying to install the new nVidia Driver into my machine. They have closed the rpm repository so the installation is a complex procedure now… You’ve to configure the xorg.conf file, then close the X server, and then, another problem may arise if you don’t have any precompiled kernel but only the binary image of it. I had, unfortunately nVidia installation software stopped me right there and as it was very late, I was gearing up for bed, then the bolt came from the blue.

I tried to restore my X server back by [ALT+F7] and it failed, giving a quick and scrolled error message. What I guessed that, It has something to do with what I’ve changed.

/etc/X11/xorg.conf

I just checked, what was wrong with that, ( I had my command line shell )and I found I’ve left the server name in

Section “Device”
Identifier  “Videocard0″
Driver      “nvidia”
EndSection ,

The root of the problem was the word, nvidia. Which I recalled, earlier was, nv. Actually what happened, HAL didn’t find any device named nvidia… that’s it so X server failed.

I changed that. and restarted.

Everything worked fine, until the login screen. I was shocked to see that my keyboard is not working!

I logged into my root accnt by help of on-screen keyboard and again oened the xorg.conf file. There I found,

# keyboard added by rhpxl
Identifier  “Keyboard0″
Driver      “nvidia”
Option        “XkbModel” “pc105″
Option        “XkbLayout” “us”
EndSection

How silly of me… I’ve mistakenly put the keyboard driver also as nvidia which was earlier, intuitively, “kbd”

I changed that and restarted again.. and Whoa… Life is peaceful once again.. !

Motto of the text : Always have a backup file while tweaking with system files !

Hope this experience will someday be a help to you… Signing off… Need a sleep seriously… … Good Night… or rather, mornin’..

Love you sweetheart…

LZW Compression and Decompression

I was kinda down for last 4 days, thanks to BSNL broadband service. I missed several classes at #dgplug and missed talking and discussing with friends. But still, I tried a C program on Lempel Ziv Welch Compression and decompression Algorithm.

Actually I made it for one of my very special friends, who is currently at IIT Bombay doing her tiresome Project work. Though, the Algorithm wasn’t anything to give trouble, I missed perl and python very much.

After 3 hours of non stop coding and then 5 (!) hours of debugging session, I made it.

I’ve uploaded the code into my svn account at dgplug…

Since then, I’m thinking about making the LZW Algorithm even more effective.

Something’s going to come up in few days. Watch out for that.
