This problem seems to affect me on Lucid Beta, too. But I had no problems using the Radeon driver on Karmic. Maybe 3D effects of KDE overheat my GPU, even if there are no effects rendered for a long time! My temperature sensors report temperatures up to 95 degrees celsius and one time my notebook switched to emergency off, after the fan raced at full throttle for some minutes.
Maybe, the following is another critical bug, but I noticed xorg to consume up to 40% CPU load (2x2,4GHz AMD ZM-86) for several minutes. Often that was initiated by watching some long videos on YouTube in Firefox, while Kaffeine runs showing live TV advertisements. Ok, Kaffeine and npviewer consume much CPU (25% each), too - but when the problem starts, the YT video is only shown @~1-2 fps and even after killing firefox (and so npviewer is closed), kwin and xorg show a very high CPU usage (~40% for each) with "top". That makes my Notebook unusable with Lucid and I have to reboot or wait several miniutes, until I can do simple things at a normal speed... I can not understand why this bug is on medium importance, when hardware is potentially damaged and when it makes the whole system unusable... -- [RV620] No power management with ati driver https://bugs.launchpad.net/bugs/373669 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
