Besides what Krish told you, you should disable effects in Ubuntu preferences->appearance. Otherwise you'll have a window without border. Also, you should turn on Auto redraw in TKSurfer.

Notice that setenv is for csh, if you are using bash you should do export doublebufferflag=1 tksurfer

Hi giovanni

Could you try with

setenv doublebufferflag 1

and then run tksurfer again?

Dear freesurfer users,

...

I've just installed freesurfer on my PC and I tried testing it using the sample subject. tkmedit works fine, but with tksurfer I see the window where the image should appear but no image.

the error I have is: no open gl window. I'm using Ubuntu 8.10 version with a Intel Q45 graphic card.

Somebody can help me solving the problem? thank you in advance, giovanni _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
