Well, I don't know if there is a different video driver for you to try. Frankly, I just think the video of a virtual machine is just not going to cut it. For proper graphics, you really need a full, "real" Linux machine.

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?

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. --sarah -----Original Message----- From: Paul Raines [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 28, 2007 10:27 AM To: Sarah Andersen Cc: freesurfer@nmr.mgh.harvard.edu Subject: Re: [Freesurfer] problem viewing in tksurfer 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.

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.
