[CX700] OQO Model 02 Default Xorg Configuration Issue

[Gilbert Mendoza]

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.

For sake of completeness... BusID "PCI:1:0:0" is NOT needed for it to work. The VBEModes option however is required.

Section "Device"
        Identifier "Configured Video Device"
        Driver "openchrome"
        Option "VBEModes" "true"
EndSection

I'm changing the status to Triaged.

Thank you.

I think this ought to be fixed now. Can you test with a recent Ubuntu release (or test against Jaunty if possible - ISOs are available at http://cdimage.ubuntu.com/releases/)

[Bartosz Kosiorek (gang65)]

Please build latest Openchrome according to
https://help.ubuntu.com/community/OpenChrome

or try install Ubuntu 9.04 Jaunty.

It should fix this problem.
