In my case, logout-and-login trick didn't work for me. However, after some frustration, I remembered that I chose "keep local version" option on updating menu.lst. (I was currently on the old kernel, 2.6.28-16.) When I changed the menu.lst to boot on the new kernel, 2.6.31-14, the problem has gone (amazingly) and xorg keeps CPU usage at around 0.9%.
My system is T61 with Core2Duo 2GHz, Intel 965 video, 500GB HDD and 4GB RAM, Ubuntu 9.10 32bit. Hope this is useful to someone. -- High Xorg CPU usage? https://bugs.launchpad.net/bugs/449196 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
