Public bug reported:
Binary package hint: xorg
When xorg fails to detect display, it forces to use 640x480. This happens even
if xorg.conf contains relevant information for the display. If the recognition
fails, it should consider using xorg.conf information.
The quick solution:
user should be provided a way to disable automatic recognition and force to
use xorg.conf settings? Override already possible?
SW Version: ubuntu 8.10
Hardware:
HP 2133
P/N: FU337EA
Bios: F.05 (happens also with 03 and 04)
Display native resolution: 1024x600
