The technical board voted for compiz by default for Ubuntu 7.10! This is a very exciting step. Compiz (and the fusion plugins) will be enabled for new installs on all hardware that supports it. A lot of work was put into making this happen, a special thanks goes to the great compiz and compiz-fusion community.
We now need the help of the ubuntu community to find bugs and issue with this new default. Please test current gutsy livecd images. If you run gutsy already, please enable compiz (System/Preferences/Appearance/Desktop Effects) and report any problem to the launchpad bug tracker. We will have to disable it on some hardware because its either too slow or the drivers are not yet good enough to make it a pleasant experience. Real world testing is essential to figure out which ones. It is important that we get as much test coverage as possible on a wide variety of hardware at this stage of development. Please help and report bugs!
