You can try installing the ATI proprietary driver (fglrx, Catalyst) instead of using the open source driver that come with Ubuntu. Check to see if this driver is compatible with your card.

I've had nothing but trouble and bad luck getting ATI graphics cards to work under linux. If building from scratch, I install an NVidia graphic card. Their proprietary drivers seem to have fewer problems. You can get a capable GeForce card for $30-$40 if you don't want 3D stereo.

Cheers,

Hello all,
I installed ubuntu 13.10 on my PC. It has ATI Radeon HD 4650 graphics card.
When I am trying to load a pdb file in PyMol, It gives following error.
Which drivers do I need to install?
