I am experiencing this also on my Pentium M / Radeon x300 laptop. My coworkers laptops (Gentoo, Fedora Core 5, Centos) are all stready at 99% idle in the same situation, where as I am all over the place 10 - 100% idle.
My entire desktop is sluggish because of it. I've tried using both the 'ati' and 'radeon' drivers. -- Default desktop is too cpu hungry when idle. https://launchpad.net/bugs/44912 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
