[Chimera-users] chimera error

[Greg Couch]

First double check that OpenGL is installed and working by runging 
/usr/bin/glxgears.  And then if that works, submit bug report to 
chimera-bugs at cgl.ucsf.edu with the output of the glxinfo program and the 
CHIMERA/bin/linuxdist program as well as the backtrace you've included 
here.
