I hope that the drivers for my laptop get better by the time I'm forced to start using this new window manager.
18 months ago, I bought a laptop with an Intel GM965 video card. This is supposed to be one of the amazing Intel graphics cards that "just works". It has not lived up to this expectation. Currently I can run stellarium, but celestia and anything based on clutter runs at a pitiful 1 frame per 3-4 seconds, when they are lucky to run at all, rather than causing X to segfault.
Now that Intel's newer graphics cards have gone all proprietary, I doubt this situation will ever improve.
