Setting up Samsung 2443 monitor - 1920x1200 (60Hz) on Ubuntu 10.

OK so I just installed Ubuntu 10.04 with ATI's fglrx proprietary driver on my HP 6930p with Samsung 2443BW 24" monitor but the screen resolution got stuck at 1280x1024. Here's how I made it to work in its native resolution.

You can either use root or just add sudo before each command.

root@ubuntugekko:/# xrandr --newmode "1920x1200_60" 193.16 1920 2048 2256 2592 1200 1201 1204 1242 -HSync +Vsync

If you tested it and it works, then create a file in your home directory called .xprofile with the following in it:

prana@ubuntugekko:~$ cat .xprofile

xrandr --newmode "1920x1200_60.00" 193.16 1920 2048 2256 2592 1200 1201 1204 1242 -HSync +Vsync
xrandr --addmode CRT1 "1920x1200_60.00"
xrandr --output default --mode "1920x1200_60.00"

Done
