Hi Eric,
some info in this recent thread too.

Thanks for the pointer. I must have skipped over that thread. The
problem described there looks like what is happening to me (I'm glad I'm
not the only one!) Following Robert's suggestion to look into changes
made to GraphicsWindowX11.cpp, I reverted back to r12292 and everything
seems to work reliably, and now I'm working forward. There were a pretty
major couple of changes r12293 and r12294 and that's what I suspect
caused the problem. The only other change to this file after then was
r12339.
I saw the discussion of making the viewer single-threaded, which of
course is not a long-term solution. Did anyone find anything in their
digging?

Yes, this is what I mean. X11 itself crashes and restarts. One of the
weird
issues is that this happens only for OSG trunk, not for OSG 2.8 svn,

I doubt it has anything to do with GL3 as the svn/trunk doesn't do
anything special
for GL3 unless you compile the OSG specifically for the GL3 subset.
Ok, thanks for the info.
There have been a few changes to GraphisWindowX11.cpp since 2.8.x so
you revert these to see if
one of the changesets is the culprit. It could be just a co-incidence
though, sometimes threading
problems can appear and disappear just with slight changes in timing.
I'm afraid I'll have to leave it
to you to try out different versions of GraphicsWindowX11.cpp as I
can't reproduce the problem at
my end so have no way of know which changes might be introducing
problems.
Well I'm making some progress. After updating my nvidia driver X11 no
longer crashes, but osgviewer still does. I'm going to try this on
another mac machine also running Fedora 14. Anyone else using Fedora 14
out there? I'll try messing with GraphicsWindowX11.cpp next.
Eric
