Hello,

I'm trying to display the inflated surfaces through mne\_analyze/tksurfer and all I see is only few pixels of the surfaces. I'm assuming this is a problem with graphics, so I think I have Matrox Graphics (MGA G200ew WPCM450 rev 0a) installed on my host machine and I'm accessing this machine through VNC.

Thanks and Regards,

---

Hi Santosh,

This is common problem when accessing brain surfaces through VNC I think  
you have Local windows terminal to acess Linux machine through VNC.  
Try typing $MNE\_ROOT/bin/mne\_opengl\_test to check your opengl performance  
over VNC.
