Why do you have lower resolutions setup for 16 depth than 24. I believe
the resolution needs reduced when greater color resolutions are used. I
do see the default depth is 24 and this is where your 1024x768 is set.
I have a dell with an Intel 865G that works fine at both 1280x1024 and
at 1024x768 using the depth of 24.
Excerpt from your xorg.conf file posting:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 16
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
For this section, I am confused as to why all of the commented
information followed by redundant information as the excerpt describes
below:
Section "Monitor"
### Comment all HorizSync and VertSync values to use DDC:

Have you changed any settings in BIOS or upgraded the BIOS version lately?
I have seen the problem that you describe on several different
videocards. The problem usually appeared after a 3D application was
launched. Then the video information would pan as you are experiencing.
You might try to rename your xorg.conf file and run
system-config-display --reconfig. Check all hardware settings and ranges
to assure they are correct. Save the config file, then restart X.
If your video settings are still not correct, system > Preferences >

Good luck, the video chipset is not busted for me, but I do not use a
monitor as you have.
