Now that some of the vendors (eg. Lenovo) have finally begun to announce laptops with Quad Core Intel CPUs, I am going to be keeping my eye on the configurations available from the vendors. I will be needing to replace mine (Dell) later this year and am very loathe to get another nVidia GPU given my current disposition. Even if it means going with an Intel GPU that uses shared system memory, given that the Intel drivers are open source. Though I will also keep an eye on the ATI cards and the feedback on those, given all these issues. > We're both on Ubuntu 7.10 (I may have lied and said 8.04 earlier), > and I'm a minor kernel revision ahead of him.

If it is not the 1.5 devel version that Fedora 9 uses, that might be why your behavior is somewhat more stable. Besides the longer standing bugs that nVidia has yet to fix relative to Compiz, the new Xorg version that Fedora is running really messed things up and nVidia has been rather slow to get up to speed. That is despite the fact that the new Xorg ABI has been stable and published for some time. >> I agree with Duncan in that you should disable any of the >> compiz/compiz-fusion features, which add significant overhead and put a >> strain on the graphics drivers.

From what I have read it seems to be X11/X.org, so should affect most Linux users *who are trying to use fancy OpenGL stuff on their desktops* -- perhaps the reason we keep here from Ubuntu'ers is that compiz is on by default in newer releases? I'd be happy to be set straight by anyone using rgl successfully on other Linux distributions simultaneously with OpenGL desktops ...

Opposite problem here - my PC has nVidia graphics with the proprietary driver, and the only problem is the mouse action on the rgl window. M'colleague has Intel graphcs and his rgl window is mucked up beyond all recognition (no visible window decor, no repainting when you move it, and so on).

Re: [R] rgl/compiz problem
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.
