I just bought a 22" LCD (LG Flatron L226WTQ) with a native resolution of 1680x1050. I am running Ubuntu Gutsy (7.10) on two laptops that contains the following versions of the drivers: xserver-xorg-video-ati - 6.7.195 ATI Graphics --------------- On the T41 (with ATI graphics, radeon RV250), the desktop is shifted 2 inches to the left. Hitting the "Autoset" button on the LCD fixes it momentarily, but then it goes back to being shifted. I am using the VGA connector to connect the monitory.
Created attachment 12086 [details] [review] Xorg.0.log file with ATI driver from git 10.16.07

This is an xserver bug. There was a bug in xserver 1.3 that reversed the sync polarities of the data from the edid. you'll have to patch or update you xserver or add new modes to override the ones from the edid.

I have a ATI 9250 on the L226WTQ and had the same problem (also Ubuntu 7.10). Check this out: http://ubuntuforums.org/showthread.php?p=3591813 I hope it works for you too. Greetings, Michael

But inserting two lines is much faster and easier and solves the problem immediately. Anyway, I will try to find a better solution, that means finding a way that Ubuntu releases a newer version of X server.
