I have the exact same problem with ATI HD 4850. I normally don't use linux, and I'm trying out Ubuntu just today... a bit disappointed with the graphics issue. Without the proprietary drivers, everything is too slow (and I can't choose my monitor's native resolution), so really need those drivers to work.
On my AMD x4, I get 1 core at 100%, 1 core about 90%, and the other two cores idle. top shows Xorg at 100%, so I killed Xorg, X restarted, and things were back to normal. By the way, not sure why this is marked as incomplete and tagged as needing Xorg log. A previous commenter attached Xorg log. -- Display Preferences causes 100% CPU usage and does not open correctly https://bugs.launchpad.net/bugs/366757 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
