Xorg and via unichrome

[Pazzeo]

Hi all,

I have installed the via unichrome downloaded from this link http://linux.via.com.tw/support/downloadFiles.action. Following the instructions xorg start correctly now. But in the log file I see these errors:

I think the big problem is that the /dev/video2 is not found.
How can I solve these errors? What kind error is the QPainter::setCompositionMode: PorterDuff modes not supported on device ??

Thank you
