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!
