I am trying to run pymol on a notebook (olivetti 550) under Ubuntu 12.04. The notebook has the SIS 771/671 graphic chip.
The PyMOL screen flickers including the internal gui. I manage to install the drivers from here https://github.com/hellnest/xf86-video-sismedia-0.9.1
and get the correct resolution but PyMOL is still flickering. I try ubuntu 2d and ubuntu 3D. Any idea of how to fix this?
