It seems that you are using running this Centos inside a VMWare. TkSurfer works fine in Virtualbox (2.1.4) but I'm not sure it'll do in current vmware

Attached is the output of dmesg. I am not very familiar with evaluating the output of glxgear. Here is a sample of the frames per second that is printing:

7920 frames in 5.0 seconds = 1569.891 FPS 8280 frames in 5.0 seconds = 1654.312 FPS 7920 frames in 5.0 seconds = 1576.902 FPS 8520 frames in 5.0 seconds = 1688.239 FPS 9000 frames in 5.0 seconds = 1789.300 FPS 8520 frames in 5.1 seconds = 1683.927 FPS 8359 frames in 5.1 seconds = 1650.856 FPS 8280 frames in 5.0 seconds = 1653.440 FPS 8280 frames in 5.0 seconds = 1643.529 FPS 8040 frames in 5.0 seconds = 1599.484 FPS 9227 frames in 5.1 seconds = 1825.203 FPS 8760 frames in 5.1 seconds = 1732.738 FPS 8160 frames in 5.0 seconds = 1630.169 FPS 8400 frames in 5.0 seconds = 1677.716 FPS 8520 frames in 5.0 seconds = 1701.086 FPS 8021 frames in 5.1 seconds = 1587.792 FPS

Hi all,

I am running freesurfer on CentOS (5.2-x86_64). I get the folowing error when I launch tksurfer: surfer: ### redraw failed: no gl window open. The result is that no surface is shown.

Any advice on how to solve the problem?

Thanks, Elisa
