[Openchrome-users] Black screen with direct rendering and cle266

[Peter Andersson]

Hi, i am trying to get direct rendering to work with a via cle266. X
starts allright when dri is not enabled but when i start X with "Load DRI"
the screen turns black and nothing else happens. The screen doesn't go
into powersave or loose the signal from the graphics board it just turns
black. Otherwise the computer seems to be working fine, i get no lockups.
In order to get back functionality of the monitor i have to connect to the
computer and reboot it via ssh.

dmesg outputs this:

[drm] Initialized drm 1.0.1 20051102
[drm] Initialized via 2.7.4 20051116 on minor 0
agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0.
agpgart: Putting AGP V2 device at 0000:00:00.0 into 4x mode
agpgart: Putting AGP V2 device at 0000:01:00.0 into 4x mode

So there are no obvious errors here...

The Xorg.log doesn't list any errors either. But i do get many warnings
like these:

(WW) (1024x768,Monitor0) mode clock 65MHz exceeds DDC maximum 0MHz
(WW) (640x480,Monitor0) mode clock 36MHz exceeds DDC maximum 0MHz

And when X is started (although the screen is still black) it starts up
with 640x480 mode with a virtual desktop of 1024z768.

(II) VIA(0): Attempting to use 85Hz refresh for mode "640x480" (112)
(--) VIA(0): Virtual size is 1024x768 (pitch 1024)
(**) VIA(0): *Built-in mode "1024x768": 0.0 MHz, 68677.8 kHz, 85.5 Hz

(--) VIA(0): Display dimensions: (360, 270) mm
(--) VIA(0): DPI set to (72, 72)
(II) Loading sub module "fb"


Basically i have no idea on how to proceed. So if anyone has any clue
please give me a hint. I have included my system specs and xorg.conf below.

Thanks
