I don't think it is possible for an application like DrRacket to do this on Linux. Which free graphics driver are you using? My guess is that the default for Ubuntu is the Nouveau driver. Based on a quick Google search[1], it seems like one possibility is that the 10.04 drivers are just too old for compositing and that the 10.10 or newer ones might work. You could also try a PPA that provides newer graphics drivers: https://launchpad.net/~ubuntu-x-swat/+archive/x-updates And the Nouveau wiki for more info: http://nouveau.freedesktop.org/wiki/UbuntuPackages Cheers, Asumu [1]: http://ubuntuforums.org/showthread.php?t=1560343 ____________________ Racket Users list: http://lists.racket-lang.org/users
