Re: SiS 671/672 Graphics: OpenGL/3D driver
you can try this, it's in french, you have to install the old driver and change the Xorg file, as shown here:
I have a 1280 x 800 laptop with onboard sis mirage3 graphics chipset on Mint 12.
This worked a treat after returning to this problem time after time and the solutions never quite going according to procedures described for modding Xorg.conf or xrandr methods etc, tried on Ubuntu, Suse, Xubuntu CentOS and Mint
The instructions are simple even if you can't read french as the code is in terminal english.
If you have a 1280x800 just follow all the command lines one by one untill you run the linerestart.Code:make install
et voila! (Well,it did for me anyway)
If you have a 1366 x 768 screen just continue following the next 2 steps to define xorg.conf, although I can't vouch for this one
