I have just encountered the problem with rgl where plot3d figures don't interact with the mouse. My plots zoom in and out with the mouse wheel but the mouse buttons do nothing. I can't rotate the plot. 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: """ unfortunately rgl and compiz/etc. both try to use the same OpenGL interface, so you can't use both at the same time. """ 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? 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 Barry
Two days ago I installed compiz on my Debian laptop. It plays fine with the OpenGL games that I also have on that computer. (My son plays the games in the brief interludes between my intense R hacking sessions. I, of course, have no time for such frivolity. The production cycle is sleep -> eat -> R -> eat -> R -> eat -> sleep.) I can rotate and zoom using the touchpad, when both rgl and compiz are running. Not sure if any of this is of help, Simon.

So I'd suggest you turn off compiz or switch to a reliable OS like Windows ;-). Duncan Murdoch> Google Earth works fine, and I think that uses OpenGL.
