I recently started getting this error message when running tkmedit:
GLUT: Fatal Error in tkmedit.bin: failed to create OpenGL rendering context.
This is with v4.4 on a machine running RHE5. Recent updates to RHE5 may be to
blame.
I get this error when running v3.0.5:
freeglut
(/space/monkeys/1/pubsw/packages/freesurfer/RH4-x86_64-R305/bin/tkmedit.bin):
Unable to create direct context rendering for window 'Medit: '
This may hurt performance.
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 143 (GLX)
Minor opcode of failed request: 5 (X_GLXMakeCurrent)
Serial number of failed request: 37
Current serial number in output stream: 37
I see that there have been previous posts about similar errors, but I haven't
found any replies with solutions.
tkmedit does work when I use a different user account than the one I log into
the xserver with. In that case, I get these messages:
NVIDIA: could not open the device file /dev/nvidiactl (Permission denied).
freeglut
(/space/monkeys/1/pubsw/packages/freesurfer/RH4-x86_64-R305/bin/tkmedit.bin):
Unable to create direct context rendering for window 'Medit: '
This may hurt performance.
Does anyone know of a solution for this problem?
