Should have said "installing the NVidia libGL.so".<br>

You are correct to suspect a Mesa library problem. We have worked
around the remote display problems before by installing the NVidia (and
dependencies) on the remote computer. If you don't want to override
the system version of libGL.so, then put it in a different directory
and set the LD_LIBRARY_PATH environment variable to that directory
before running chimera.<br>
<br>
If you want to try an isolate the part of OpenGL that is causing the
problem, start chimera with the --debug-opengl command line option and
press the Disable All button to disable many OpenGL features, and then
Start Chimera. If opening a PDB file works, then you can experiment
turning OpenGL features back on until chimera fails again. You can
speed up the search if you're familiar with OpenGL and start chimera
with the --debug command line option -- in that case, it should
reliably fail in the same place and the error message should indicate
the part of OpenGL that is causing problems.<br>
<br>
As for running chimera on NX client, I didn't see any mention of OpenGL
support on the NX Server feature page, so you're probably out of luck.
If you want to display remotely on a Windows computer, you can install
a X server that supports OpenGL, like Xming or Exceed 3D.<br>

Can this be fixed? (We suspect it's a mesa library problem).<br>
<br>
Also when running nx client, even the old version of chimera from
crashes.<br>
I'll have to get the error message later, but does anyone have
experience running over nx client?<br>
<br>
we've gotten pymol, and vmd to work.<br>
