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

thanks,

Try running glxgears

Can you post the output of dmesg command

Thanks you. I actually tried this already (I saw this solution was suggested to users that experienced the same problem). Unfortunately this is not working, I still get the error message:

surfer: ### redraw failed: no gl window open

Is there anything else that you would suggest to try?

Thank you in advance,
Elisa

If you are using
tcsh

setenv doublebufferflag 1

in bash

export doublebufferflag=1

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
