Hi Ben,

Yeah, integrated graphics generally don't fare well with FBOs or
pbuffers. Hopefully it shouldn't crash though, it should tell you it's
not supported and exit...
osgprerender cow.osg --pbuffer.
This results in segmentation fault. Even without the --pbuffer option
it results in segmentation fault.
So yes sorry for bothering you much Rob. It is not a osgdem bug.
However, it will be great if you can suggest a workaround or solution.
Does Mesa support pbuffers or FBOs? It would be completely software,
thus slow, but it might work...
osgdem really needs a graphics context to do some of its processing, and
in order not to pop up a graphics window it uses pbuffer rendering, so
the only other alternative would be to get a better graphics card
(though that looks like a laptop so you would probably need to run
osgdem on another machine that has one).
Correct. This is a laptop. My desktop with a GeForce graphics card just
broke a week ago :( and I'm too busy to fix it. But this is completely
off-topic.
Instead I think I'll just try to hack with the newest release of
graphics driver but I really doubt it'd work.
The entire X11/GLX stack is very confusing btw.

Thanks,
