Glenn and Lars,
I don't have any real suggestions to try, other than replacing the word 'Disable' with 'false' in that xorg.conf section. But that seemed to apply only to Nvidia cards, and was intended to solve another problem (a 'BadMatch' error on startup of qdec).
We have not seen the problem you are seeing on our Centos 5 systems with ATI X1400 Mobile Radeon video cards, using the newest driver downloaded from ATI (I don't have the version on-hand). So this will be tough one to debug.

Hi,
I am experiencing similar problems to Jennifer with tksurfer; the key (tksurfer) error message being surfer: ### redraw failed: no gl window open and the display showing only a thin slice of the posterior of the surface.
The computer is a fresh install of RHEL 5. Matlab is NOT (yet) installed on the machine. Specifically:
freesurfer-Linux-centos4_x86_64-stable-pub-v4.0.4 subjects$ sudo /sbin/lspci 01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series] 01:00.1 Display controller: ATI Technologies Inc RV516 [Radeon X1300 Pro] (Secondary)
I just yesterday updated the video driver: $ yum -y install fglrx64_7_1_0 initscripts-atidriver and auto-configed the X11 server $ aticonfig --initial=dual-head --screen-layout=right The tksurfer problem occured with the autoconfiged xorg.conf file, which is at the end of my message. Adding
Section "Extensions" Option "Composite" "Disable" EndSection
didn't help (I tried this only for completeness, I do not know if "composite" is an option on ATI cards).
