Joao,
Make sure your graphics driver is up to date. Also make sure that 'glxgears' runs properly on your system. That exercises the OpenGL X driver.

Hello,
I'm having an issue with tksurfer - whenever I try to load a surface, the display only shows scattered points (with the vaguely recognizable shape of the intended surface). I've noticed the following error that may be related to this:
libGL error: open DRM failed (Operation not permitted) libGL error: reverting to indirect rendering
I'm using the freesurfer-Linux-centos4_x86_64-stable-pub-v3.0.2 version. Any ideas as to what is going on?
Thank you very much for your help.
Best,
Joao Pereira
