Dear freesurfer list

I know similar problems have arisen before and I have read the archives. e.g. http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg07545.html http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg07324.html

however I'm still not sure how to solve my problem so here it is:

tksurfer only displays a sliver of the brain (on my windows laptop with NoMachineNX viewer) it displays nothing using a xterm on a Mac G4.

here's the output -bash-3.2$ tksurfer atm lh inflated surfer: current subjects dir: /local/jdubois/fMRIdata surfer: not in "scripts" dir ==> using cwd for session root surfer: session root data dir ($session) set to: surfer: /local/jdubois/freesurfer surfer: Reading header info from /local/jdubois/fMRIdata/atm/mri/T1.mgz surfer: vertices=137024, faces=274044 Loading /opt/freesurfer/surface_labels.txt surfer: ### redraw failed: no gl window open surfer: single buffered window surfer: using interface /opt/freesurfer/lib/tcl/tksurfer.tcl Reading /opt/freesurfer/lib/tcl/tkm_common.tcl Reading /opt/freesurfer/lib/tcl/tkm_wrappers.tcl Reading /opt/freesurfer/lib/tcl/fsgdfPlot.tcl Reading /opt/freesurfer/lib/tcl/tkUtils.tcl Successfully parsed tksurfer.tcl reading white matter vertex locations...

tkmedit works fine however

there's nothing in .xdebug_tksurfer

Server specifications: Graphics card: ATI Rage XL (http://ati.amd.com/products/server/ragexl/index.html) GL library: mesa-libGL*-6.5.1-7.5.el5 It is noticeable that it used to work before an OS upgrade was done on the server.

I have the same problem with 2 other servers (Dell PowerEdge with ATI RN50 according to Dell, which is apparently the same as ATI ES1000). Same GL library.

WHAT CAN I TRY TO DO?
