Hello,
1. No image would display in Anatomist. An error message "no GL list" apppeared on the console.
2. Running glxinfo revealed "direct rendering: No"
3. The Problem was solved by moving libGL.so* away from /usr/X11R6/lib: this Mesa lib prevented the nvidia libGL to be used...
(thank you Denis!)

Yes, just a few precisions:
- this kind of problem only happens on machines with nvidia 3D cards and nvidia driver
- it only happens on linux distribs that still have OpenGL libs in /usr/X11R6/lib instead of /usr/lib (the standard place now)
- it is caused by the nvidia driver installation which replaces the system OpenGL library by one from nvidia, but the installer only looks for the system lib in /usr/lib, not in /usr/X11R6/lib, so it doesn't correctly remove the library if it is located there, and the wrong one gets loaded at run-time.

libGL problems as well
Hi,
I have the same problems and moving libGL.so* out of /usr/X11R6/lib does not help. I still cannot visualize anything.
Any ideas?
thanks

If you have installed the nvidia driver, you can check if it works using glxgears (if it is installed on your computer). The speed is very high if the driver works :
[manik@pclx8 testData]$ glxgears
28771 frames in 5.0 seconds = 5754.200 FPS
Could you give more information about what is installed on your computer and what you do to see the problem ?
