Check:

1) The resolution of monitor in Fedora FC12 and color depth
2) The drivers for your video board (ATI/NVidia)

Hi FreeSurfer Experts,

I am working on a cluster which ran until recently on the Linux OS Fedora 4. Since the upgrade to Fedora12 I can no longer launch tkmedit whereas it worked fine on the previous OS(fedora4).

The following error appears:

GLUT: Fatal Error in tkmedit.bin: visual with necessary capabilities not found.

Any suggestions would be helpful

Thanks in advance.

Mohammed
