Dear Freesurfer users,

Has anybody tried to run FS with ati video cards? I am asking because I am completely stuck with it... At the beginning everything was good except the bad brain displaying with "$rh pial" command (FS displays only a small piece of it). I decided to reinstall my videocard driver

am providing you my report:
