[chimera-dev] Xlib: extension "NV-GLX" missing on display ":0".

[Tom Goddard]

Hi Thomas,

   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.
