[Chimera-users] no moleculr dispay with version 1.8

[Robert Wohlhueter]

I have chimera-1.5.3 running on my Linux-AMD64 Ubuntu (12.10) computer.  
It works fine in every respect.  Recently I installed version 1.8, with 
runs, but with one fatal flaw.  By "runs", I mean the chimera screen 
comes up, the menus display.  If I load (say, a pdb file), it seems to 
be there in the sense, for example, that I can open and view its sequence.

BUT the molecule display window is absolutely blank (black).  I suspect 
it has either to do with my python installation, or with my NVIDIA 
graphics driver. But whatever the problem, it effects only v. 1.8, not 
v. 1.5.3.

For NVIDIA driver I'm using version 310.14.

For python, I understand chimera uses 2.7.  My python executable is 
indeed set as version 2.7.3 (that is, `python --version1 returns 
2.7.3),  though I have version 3 installed, and it could be used, if 
needed.  I'm not all so clear on how envars PYTHONHOME and PYTHONPATH 
may or may not effect chimera.

Of course, the easy way out is to stick with chimera-1.5.3 -- but one 
likes to stay up-to-date.

Thanks in advance for any profound wisdom.
