When I run dypyinfo, it lists both GLX and SGI-GLX. Does this mean that I still need to install a X11 video driver? Or is it a different problem?

Thanks again,

sarah

It should have been xdpyinfo, not xdpyino (note the 'f').

Thank you.
 
When I run 'xdpyino | grep GL' it says "xdpyino: Command not found" (this is
in the tcsh shell)
 
I am running it on VMware Player version 2.0.2 and using the FSL_vm5_32
virtual machine from the FSL website. If this helps and you can give me
further instructions, I would greatly appreciate it. Otherwise, thank you
for the help that you have already given.

Your X server on your virtual Linux image does not appear to have GLX
support.  If you run 'xdpyino | grep GL' do you see GLX listed?
 
If not, I am not sure what to say as I don't know what virtual machine
program you are using.  But you need to read up in its docs about
how to properly install a X11 video driver for it.

Dear FreeSurfers,
 
 
 
I am having a problem viewing  in tksurfer: I can only see a sliver of the
brain. This sliver will rotate and do everything that tksurfer is supposed
to do, but I can't view any more of the brain than a tiny piece of the
occipital lobe. I have tried this with several different files, and had
 

the
 

same issue for each of them. Tkmedit, on the other hand, works fine.

In the email archives I have seen a response that mentioned the NVidia

Thanks in advance for the help!
