Today I upgrade few machines to Jaunty Jackalope 9.04. However in machines with Intel's graphic driver I faced two kind of problem with compiz. Problem 1: After upgrading to Jaunty, compiz couldn't be enabled. The error was saying that the driver was backlisted. To solve this create a file ~/.config/compiz/compiz-manager and put SKIP_CHECKS=yes Now enable compiz and it should work. Problem 2: After upgrading to Jaunty, compiz is very slow. You'll easily notice the performance degradation. To solve this you can revert to intrepid driver by following https://wiki.ubuntu.com/ReinhardTartler/X/RevertingIntelDriverTo2.4 But what I did was used "UXA" instead of "EXA". UXA is new and far better but this has some bug, which prevented it from being default in jaunty. To do this open your /etc/X11/xorg.conf and add Option "AccelMethod" "uxa" under Section "Device"

I was going through an article and found one interesting piece of information presented below. When Ubuntu was created back in 2004, Mark Shuttleworth recorded the very first bug in the online database. However, it wasn’t about software. Instead, it was a revolutionary call to arms. It read as follows: “Microsoft has a majority market share in the new desktop PC marketplace. This is a bug, which Ubuntu is designed to fix”. You can read it yourself here, https://bugs.launchpad.net/ubuntu/+bug/1
