Re: [Freesurfer] remote access

Leila,

Make sure your Windows video graphics driver supports GLX. To test this, once you've made a remote access connection to your Linux box, run the utility 'glxgears', which should be installed on your Linux box (not part of Freesurfer). You should see a spinning gears app.

Also, if you Linux box has an NVidia graphics card, make sure the driver is up-to-date.

Hello,

I tried to do remote access from my windows xp computer to the linux one, I follows the steps described in the freesurfer web pages. The remote access seems work correctly, but when I try to run freesurfer (tksurfer) it does not work, this is the error:

Someone can help me??

I already installed vncviewer, the vncserver.glx and xf4vnc.

Thanks in advance
