Hi,

FreeSurfer rendering under VNC is very slow and sometimes not possible. You may try UltraVNC (freeware - worked with me once) that has a better OpenGL support.

I strongly recommend that you install a local copy of FreeSurfer and use it to visualize the data.

Best Regards,

Hi All,

I'm trying to connect to a computer remotely to use freesurfer. However, when I log in and try to load up a surface in freesurfer, I get the following message:

-No glx extension! -Surfer: failed, trying double buffered window -Xlib: extension "GLX" missing on display "computer name" -Window type not found! -Surfer: failed, no suitable display found

I am using a VNC viewer (from www.realvnc.com) to log into the computer. Are there any software rendering solutions for freesurfer so the VNC doesn't run into the openGL problems? Or, on the other hand, are there

any

VNC clients that are known to work with freesurfer?

Thank you very much!
