[Chimera-users] Daily release Chimera installation

Hi Yao (and chimera-users),

The error message should have read:

 	Display misconfiguration.  Please increase the color quality
 	(24 bit color or greater), update your display (graphics)
 	driver, and/or upgrade your graphics card.  Also see chimera
 	installation instructions.

The other common error on Linux is that your OpenGL configuration got
messed up when you updated your system.  For example, if you previously
had a NVidia or ATI graphics driver installed, then updated your system
from Fedora 10 to Fedora 11, then the updated system might be in an
inconsistent state until you reinstalled the NVidia or ATI driver.

If /usr/bin/glxgears works (in the glx-utils package) and chimera
doesn't, then please let me know and we'll dig into this deeper.
