Hi Jason,

I followed compiling instructions from http://www.pymolwiki.org/index.php/Linux_Install
Actually, first attempts were with instructions from INSTALL (setup.py build install ...) and faced same problem.
This machine is Lenovo G550 notebook with poor "Intel Graphics Media Accelerator 4500MHD" graphics, but I successfully had used PyMol on OpenSUSE.

Hi Ivan,

How did you install PyMOL? What commands did you use?

Also, what video card is in your computer?
