Quite easy actually
btw tero how hard was it to compile the driver for 12.10?
I think that was all that was required if i remember correctly
Install of Via Grafikk
install linux headers
make system ready for compile https://help.ubuntu.com/community/InstallingCompilers
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install build-essential
$ gcc -v
$ make -v
download driver from http://linux.via.com.tw/support/downloadFiles.action
cd into the mesa 7.1 folder
run sudo sh vinstall
However im not sure if the unified drivers supports the the chipset for amd and intel processors.
Seems to be a bit unclear as my xorg.0.log says it does
But on the readme in unified driver they only state the cx700-900 chipsets.
So you might be out of luck there:/
But even if the Via propietary dosent work you still have the Openchrome driver which gets shipped by default with most distro.
They should work by deafault in Ubuntu after install, and if they dont and you got cpu accel instead you can try the unified driver and see if that works.
