Thanks a lot, I have tried this one. It does not work.
I knew someone can solve this problem on a local machine by extracting a NVidia
driver files and copying it to somewhere to overwrite some original OpenGL
files. But I do not want to do this procedure on each computer in our labs.

Hi, there,
I am running the tksurfer command to view the cortical surface data as tksurfer
bert lh inflated. But I met a problem.
I only can view a sliver part of the brain. This sliver portion can rotate and
do everything that tksurfer is supposed to do,
but I can't view any more of the brain than a tiny piece. Tkmedit works fine.
When I run the command, it gave me something like this:
surfer: current subjects dir:
/home/m047599/freesurfer-install/freesurfer/subjects
surfer: not in "scripts" dir ==> using cwd for session root
surfer: session root data dir ($session) set to:

I searched the previous posts, it looks like somebody have the same problem.
There is no NVidia and native Linux system on my computer. I run tksurfer on a
virtual Linux machine using NX 3. 3. 0. 6.
I ran the xdpyinfo | grep GL, it shows that I have GLX and SGI-GLX.
I ran the glxgrears, it works, although very slow.
So, how can I solve this problem, any suggestions are highly appreciated.
Thanks a lot!
Guang
