[Openchrome-users] OpenChrome failed on Lenovo S12

[Jean Baptiste Favre]

Hello,
I've got a problem installing Ubuntu 9.10 beta on my Lenovo S12.
Investigating troubleshooting section on the website, I found:
root at lenovo:~# grep openchrome /var/log/Xorg.0.log
...
(EE) CHROME(0): Unknown Card-Ids (112|17AA|388C);

root at lenovo:~# lspci
00:01.0 VGA compatible controller: VIA Technologies, Inc. VX800/VX820 
Chrome 9 HC3 Integrates graphics (rev 11)

What is strange is that Openchrome should support it, according to the 
homepage. More, display works on the secondary screen, just as if the 
primary won't get detected.

Any idea ?
Thanks,
JB
