Folks:
On an installation that had been working, suddenly we're getting fatal
errors on starting either tkmedit or tksurfer. These appear to be errors
trying to perform X functions. Command lines and responses shown below.
I am not aware of recent changes to the environment (new software inst
Graham,
I haven't encountered this particular error. However, tkmedit and
tksurfer produce logs called .xdebug_tkmedit and .xdebug_tksurfer which
have some startup and debug info.
Is the environment variable 'DISPLAY' set to anything unusual? It
should be something like ':0.0'

Thanks for the quick reply. Relating to the info you added, here's what I see:
1. DISPLAY is set to just ":0" (ie: without the quotes, and no ".0").
Changing it to ":0.0" -- the failures occur as before.
2. The logfiles you mention show the following:

Graham,
Does an X app like 'xclock' work? If not, does xclock work if the
Freesurfer setup script is not run?

I haven't run xclock, and unfortunately (?) am no longer at work.
However,
-- Machine is running Centos 4.4
-- KDE works fine
Nick:
Still having the same trouble as reported last week. Several more tests to
report:
1. I installed 3.0.4 -- same result.
2. In addition to several other GUI apps, I ran xclock as you suggested,
looks fine.
3. I ldd'ed tkmedit. To get a realistic output I first did:
source tkmedit
.
Graham,
Your 'ldd' output from tkmedit looks identical to what I see locally, so
that unfortunately does not give me a hint to the problem.
Does the utility 'glxgears' run ok?
Also, we run v 1.0-8762 of the NVidia driver (and also some v1.0-8178).
Version info is found in /proc/driver/nvidia/ver
Nick:
Thanks for the suggestions. It's looking like the problem is not specific
to FS after all, but I'll recount the latest clues in case you hit this again.
1. NVidia version is 1.0-8765.
2. glxgears actually fails in same way as FS programs. Hmmm.
3. Color depth, as reported by GUI tools
