Hi Wouter and everyone,
I talked with upstream a bit about this AGPMode issue. It seems
extremely hardware-specific as to what AGP Mode to use. So I coded up a
quirk system that will let us build a table in the driver of ATI video
cards vs. host bridges, and the AGP Mode they need. The data on the
configurations I need for setting this is:
* AGPMode value needed
* Make/Model of laptop or motherboard
* Output of lspci -vvnn
* Is the system all factory hardware, or have any parts been replaced?
* Is there an AGP Mode in the system BIOS?
- If so, is it set to the factory default?
You can test various values of AGPMode by setting the option in your
xorg.conf's Device section like this:
Section "Device"
...
Option "AGPMode" "2"
EndSection
Possible values are 1, 2, 4, and 8.
For more details about this issue and the quirk, I've written a section
about it in this page: https://wiki.ubuntu.com/X/Quirks
