A colleague experienced this same thing. But when he exits IDL, it crashes
the system (same as you, it appears to be "logged out"). I have not
resolved
the problem as of yet (although the software opengl posted here sounds like
a very good
idea to try).
cheers,

Ah, o.k. A place to start looking! :o)
Thanks very much for the info.

I don't know if it is the truth or not, but *this* I am
prepared to believe! :-)

I used to occasionally get similar symptoms in the past (I do not
remember if it was IDL 7 or 6.4). It was not actually a logoff, but it
looked like it: the X server died, which caused it to restart at the
login screen.
I never found exactly what operations caused the crash, but I found
that it was caused by the use of hardware OpenGL. With some versions
of my graphic card's driver (fglrx, for an ATI FireGL), occasionally
OpenGL (also, occasionally, video playback) killed the X server.
In the case of IDL, an immediate solution was to switch it to software
OpenGL (in IDL 7, it lives in Window/Preferences/IDL/Graphics). It was
eventually properly fixed with a new version of the graphic card
driver, which allowed me to get back to using hardware OpenGL in IDL.

Anyone know how to set software opengl on a linux box?
