[Chimera-users] Segmentation fault when issuing chimera command

Most reported chimera bugs are due to faulty graphics drivers. So that 
is a good starting point.

The first thing to try is to confirm that the graphics driver is 
installed properly.  If you don't have the glxinfo program installed 
yet, install the glx-utils package.  Then run glxinfo and send me the 
output.  If it fails to run, then you need to fix the graphics driver 
installation.  It it succeeds, then I'll have something to go by.

I googled this problem and found in a previous message of chimera-users that this should be a problem of driver issue. Also, on the “benchmarks” link of chimera, GeForce GTX 1080 has been tested under Windows with NVIDIA 368.81 driver version.
