Comment 14 for bug 1034812

For a sis 741 , I installed lubuntu from a MinimalCD without xserver-xorg-video-sis.

I downgraded xorg:

sudo add-apt-repository ppa:makson96/fglrx
sudo apt-get update
sudo apt-get upgrade

as in http://www.ubuntugeek.com/how-to-install-amd-catalyst-legacy-drivers-in-ubuntu-12-10-quantal.html

then

sudo apt-get install xserver-xorg-video-sis
sudo reboot
