Dear Pymol Users,
I've found a problem with Pymol version 1.4.1. I am using Ubuntu 10.10 in a laptop with Intel Mobile 4 graphics controller.
The problem comes when I load any PDB file, then try to show it as a cartoon. It displays the cartoon but in black color, so I cannot see it unless I turn the background to white. With "lines" it's correctly displayed but "cartoon" or "sticks" show the same behaviour (colored black).
This only happens if I use the "set use_shaders, 1". If I don't use this command, the "cartoon" and "stick" are displayed in the right colour, but then I have problems coloring the sticks (it's a known bug : http://firstname.lastname@example.org/msg09181.html).
I don't know if this is related but immediately after loading the pdb I get this message in the pymol console :
