Bug Description
SiS 65x/M650/740 VGA adapter works strangely on high resolution.
The 1680x1050 LCD monitor is connected using DVI cable. It works properly on 1280x960 resolution.
If I choose 1680x1050, weird things happen:
* mouse pointer disappears at certain screen areas and becomes visible on other ones
* The mouse pointer can not reach the most topmost pixels and stops in 5 mm from there. Somehow clicks works properly even if the mouse pointer appears not to be there
This is on ubuntu oneiric 11.10 i386.
# dpkg -l | grep xserver-
ii xserver-
The card is allocated 32MB of memory (from the BIOS).
Attached to the bug the /var/log/Xorg.log.0 file.
The card works properly with the same LCD on other resolutions: 1400x1050, 1600x1200, 1680x1200...
It just the native resolution of the LCD (1680x1050 16:9) that does not work properly.
