compiz problem in Jaunty solved

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.

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 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"

Time to order free Jaunty Jackalope CD enjoy!!!
