TGeomanager draw opengl crash

I am running Linux FC8. I just downloaded and compiled root 5.18.00.

Whenever I use the TGeomanger Draw method with the ogl option my xserver crashes.

The errors I get are minimal. This is a clip from my xserver log file.

Backtrace:
0: /usr/bin/X(xf86SigHandler+0x81) [0x80c2f01]
1: [0x110420]

Fatal server error:
Caught signal 11. Server aborting

Has anyone else seen this behavior? Any suggestions on how to track it down?

I had loaded the wrong nvidia driver on my machine. Sorry to bug the group.
