Xorg.0.log
Hi, we are having a problem configuring 800x600 resolution display mode on the
following Intel display chipset on SuSE Linux Desktop 11 SP2. There are no
problems displaying on 1024x768 resolution. The kernel version used is the
default kernel provided by the distro (3.0.13-0.27-pae). For this testing, the
display used is a 15-inch display monitor.
On Windows 7, this chipset was able to display in both 1024x768 and 800x600.
Therefore we ruled out the possibility that this chipset only supports
1024x768.

Specifying "PreferredMode" "800x600" in /etc/X11/xorg.conf does not seem to
have any effect. The desktop still displays in 1024x768.
We have updated the kernel using the latest kotd version 3.0.57-10-pae and the
only difference we see is that the xrandr output explicitly supports 800x600
xrandr output, showing support for both 1024x768 and 800x600:

800x600 72.2 75.0 60.3
640x480 75.0 72.8
However, the results were same when we specified 800x600 in xorg.conf as per
previous testing. The desktop still displays in 1024x768.
Will attach the xorg.conf and Xorg.0.log
We are in the process of testing this on openSUSE 12.2 and will update this bug
accordingly when we have results.</pre>
