Probably you updated the kernel (or the OS did by himself) and the restricted drivers (ATI/NVidia) are not enabled by default.

I am processing a new brain on the same linux station I've been using FreeSurfer successfuly on for months now, but when I recently rebooted the machine, I got a message saying it was running in basic display/graphics mode.  I don't know why the machine went into this mode.  Now, when I try to view an image on tkmedit, I get this error:

GLUT: Fatal Error in tkmedit: OpenGL GLX extension not supported by display

I am going to try to figure out how to get the machine back into its normal display mode.  But in the meantime, I am running a reconstruction and am wondering--can I trust the stats I get in the current mode?  Is this just a display problem, or do I need to re-run the entire reconstruction once the problem is fixed?

Thanks,

Dana
