[Chimera-users] OpenGL misconfiguration & Nvidia

  I don't have any experience with openSUSE, but the "Error: API 
mismatch: the NVIDIA ..." message is not coming from chimera.  Googling 
for answers suggests that rebooting might fix that error.

 From the chimera perspective, the OpenGL misconfiguration message 
appears when there are two different OpenGL libraries installed on your 
system, usually a slow software OpenGL and a fast one that uses the 
graphics hardware.  The fact that there are two means there was either a 
problem installing the NVIDIA/ATI driver or that a system update brought 
back an additional library.

On other Linux systems, when chimera detecting this problem, it was 
fixed by reinstalling the driver (and rebooting afterwards).

     Good luck,
