for via unichrome pro cards to work in Linux(Debian user) u need to install http://openchrome.org
drivers.the method to install these drivers and editing ur /etc/X11/xorg.conf is listed below posted by me in other forum:
I also have via unichrome card.it is not supported very well in GNU/Linux.solution is to get open chrome rpms installed.I'll show u the link.
for this u first need to be root(administrator user) user.
so in the B/W screen with "$" prompt type:
~$ su -
press enter and give the root's password.
u'll get a "#" prompt
before that u need to edit ur /etc/X11/xorg.conf using nano editor like
~#nano -w /etc/X11/xorg.conf
note the space between!
now search and find the section with Section "Device"
and edit the section to fit the driver to vesa.
Section "Device" Identifier "Generic Video Card" Driver "vesa" EndSection
save the file by pressing CTRL+O ,CTRL+X save when prompted.
reboot for gnome gui.
afterwards u can download the rpms for via unichrome pro igp from:
download only these rpms:
install these rpms like:
As root user "#" prompt:
~#rpm -Uvh foobar.rpm
or by double clicking on the rpm file in Fedora.
Now again edit ur /etc/X11/xorg.conf and change the Section "Device" as follows using nano editor as earlier:
Section "Device" Identifier "Generic Video Card" Driver "via" Option "EnableAGPDMA" "On" BusID "PCI:1:0:0" EndSection
save and exit.reboot or restart X server for GUI working.
