Guang, In the xorg.conf file, I noticed one of the Display depths is '16'. This should be set to '24' to ensure full color depth.
Also, the email doesnt mention which freesurfer version is being used. In short, that tksurfer.bin link that was mentioned is no longer necessary with the new versions (4.3 and newer i think).
