Bug Description
OQO Model 02 uses the VIA UniChrome Driver, which for some reason does not work well immediately after a clean install of Hardy, and of course the initial slimmed version of Xorg's configuration file. This results in a blank screen when GDM starts, and then begins a nice fade in of white which finally envelopes the screen entirely.
The workaround appears to be simply specifying a Driver in xorg.conf. Both "vesa" by itself, and "openchrome" with an option work well.
Xorg then detects appropriate resolutions, dpi settings, etc.
e.g. Vesa Driver
Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection
e.g. UniChrome Driver
Section "Device"
Identifier "Configured Video Device"
Driver "openchrome"
Option "VBEModes" "true"
BusID "PCI:1:0:0"
EndSection
I will attached two versions of the Xorg.0.log file one when specifying the openchrome driver, and one with blank default.
