Jenifer,
We've seen this on RHEL5 platforms (although there has been no relation to fsl). A work-around is to add this to the end of your /etc/X11/xorg.conf file:
Section "Extensions" Option "Composite" "false" EndSection
and restart X (Ctrl-Backspace).
You might need to substitute 'Disable' for 'false' in the above (some drivers use one or the other).
I'm not sure why upgrading to fsl412 would cause this to start happening now though, probably unrelated. Do you have freesurfer setup to setup FSL? if so, you could try 'unsetenv FSL_DIR' prior to sourcing freesurfer setup to bypass fsl setup, to see if this really is related to fsl (which i doubt).

Hi, Running FSv405 on RHEL5. Recently obtained new error when qdec was attempted. Have successfully run qdec before on this box using FSv405. Only update made was to upgrade to FSLv412. Same error persists after restarting X. Both tkmedit and tksurfer work fine.
Any ideas how to fix?
Many Thanks, Jenifer
