Re: tksurfer display broken - Freesurfer

29 May 2008


      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 on a new machine, and I've run 
"yum update." Our university IT department also auto-updates the 
machines. Matlab is NOT (yet) installed on the machine. I have just 
installed the latest FreeSurfer and this is my first time trying to run 
it on this machine.
Specifics:
freesurfer-Linux-centos4_x86_64-stable-pub-v4.0.4
kernel: Red Hat Enterprise Linux Client (2.6.18-92.el5)
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 think 
"composite" is an option on ATI cards).
