Are you using the NVidia drivers and if so, how have you configured your xorg.conf file? It may be a hardware or a configuration issue. A fellow lab here was having a problem with no OpenGL programs running properly and odd resolution issues after installing the NVidia drivers, turned out the xorg.conf file had not been properly edited.

Dear all,
I think our earlier posting is not clear. So we would like to draw to your attention regarding our stereo viewing problem. As Dr. Paul Emsley suggested it seems to be a harware problem, we are experiencing the same problem not only using coot but other programs too. We will be thankful to you if you could anyone help us to fix the problem
for your kind information here is our system graphics card specification
256MB PClex16 nVidia Quadro Fx 3450, Dual DVI or Dual VGA or DVI + VGA.

Thanking you
vengadesan

That is a confusing message. I can't imagine how you got it if you
simply installed a binary package :-/

However, that code path does mean that Coot failed to get a hardware
stereo graphics context, which leads me to think that it's a hardware
issue, not software.

(Oh, we are talking about 0.3.3, aren't we?)

Paul.
