[Openchrome-users] VIA Chrome 9 HC DX9 on Amilo LA 1703 - partially solved

[Tobias Doerffel]

Hi guys,

after fooling around with openchrome drivers for about 6 hours on my Amilo LA 
1703 I found one of the problems why the screen keeps black when X starts (as 
also reported by Tassilo): first of all, CRT is selected as the only 
output-device (everything works well when plugging in an external monitor!) 
because the PCI-ID is not known, so I added it. Patch against 
branches/release_0_3_0:

Now it recognizes to use Panel/LCD as output-device - so far so good. However, 
ViaTVDetect(...) or ViaTVInit(...) in src/via_mode.c -> ViaOutputsDetect(...) 
seems to prevent this driver from really working (still blank screen). When 
adding "return;" after the panel-detection-code (i.e. before ViaTVDetect 
etc.) the 2D-driver basically works :)

Apart from that I've still the problem, that I can switch back to console 
(Alt+Ctrl+F1 etc.) - the screen gets blank. The machine itself is not frozen 
at this place, I can press Alt+Ctrl+Del and it restarts. As soon as I restart 
X (Alt+Ctrl+Backspace or simply log off) the machine freezes. Any ideas on 
how to solve this? Probably it should be noted that this problem disappears 
when pluggin in an external monitor! (???)

Thank you so far.
