Dear all, Thanks for all the suggestions. - checked glxinfo and the startup log of pymol and it shows the loading of the propriety GL driver for our Nvidia FX1300 (see copy/paste below) and we're not running MESA. - although...we also have this "freeglut (/usr/pymol/pymol.exe): unable to create..." error (but i never saw this since i (also) created shortcuts (in gnome) to pymol - so the 'problem' is not fixed. And if i read the text below...maybe it's not possible to fix this. - anyway...pymol shows a strange behavior: very slow startup of the tcl/tk window (but that's probably a problem of redhat/gnome...while on a Suse/KDE system i don't see this) - and further, pymol always directly switches on the transmitter of the 3D stereo...although not showing or using stereo. - off topic: we bought this linux machine(s) to replace our old SGIs since Insight became available for Linux systems, saving ourselves a lot of money (SGIs are expensive). Thanks for the help. Best, Joris
