<br>
This a graphics driver problem. Chimera fails to start because
it can't initialize the OpenGL 3d graphics. Googling nv-glx
extension fedora 17 suggests it is a problem with how the nvidia
driver is installed. Maybe Chimera is partially getting the
software Mesa driver and partially the Nvidia driver. The nv-glx
missing warning may not be the actual problem causing Chimera to
not start but is probably an indicator of the underlying graphics
driver installation problem.<br>

I am running Fedora 17 64-bit with bumblebee and akmod-nvidia on
my laptop (the original nvidia drivers could not be installed). My
GPU (not sure if this is helpful to know) is GeForce GT 650M and
after doing that workaround with the open source drivers, in order
to use the GPU I launch each program using "optirun" command (i.e.
to launch pymol "optirun pymol", otherwise I get a black screen
and the laptop automatically logs out). I have chimera production
version 1.6.2 (build 36855) 2012-07-06 17:55:00 UTC, and whenever
I run ./bin/chimera, with or without optirun, I see the small
start up window "UCSF Chimera, an Extensible Molecular Modeling
System" but after a couple of seconds chimera terminates with the
following message:<br>
<br>
$ ./bin/chimera<br>

<br>
Or with optirun:<br>
<br>

<br>
<br>
It is worth mentioning that the small start-up window disappears
after saying "initializing OpenGL". Do you have any idea what I
can do to fix it?<br>
<br>
Thanks in advance,<br>
Thomas<br>
