This has been mentioned and discussed here and in other lists before,
and the solution is to turn off Ubuntu's fancy graphics. Back in
March, Ben Bolker said:

This has echoes of when TCP/IP was in its infancy back in the days of
DOS, and only one program could access the network interface at a time
(until TCP/IP software got its act together). Is OpenGL really in the
same position now? Or is Compiz being "greedy" in some sense? Surely
two OpenGL applications can run at the same time? Or is it because rgl
is running 'within' another OpenGL window already, so there's some
nesting problem going on?
I think it's an Ubuntu bug, because nothing like it occurs anywhere
else. So I'd suggest you turn off compiz or switch to a reliable OS
like Windows ;-).

Google Earth works fine, and I think that uses OpenGL. Anyone had any
ideas since March?
I'm on Ubuntu 8.04 and R 2.7.1
