I doubt that it is a memory problem. It is more likely that the X server
is crashing due to an OpenGL problem. When you say "logged out of your
gnome session", do you mean that the X server is crashing and getting
restarted?
Try running XROI with the RENDERER keyword set to 1 and/or take whatever
measures are necessary to force the use of the software renderer.
If that makes the problem go away, you may have a general OpenGL or X
driver/configuration problem. You might try looking for updated drivers
for your video card, etc.
Also, try running the standalone GL program 'glxgears' that should be in
your distro. If that fails, then you surely have an OpenGL/X problem that
you'll have to resolve.
