Julien - poor hardware design is a possibility. Also make sure you have removed all dust from inside the computer, particulary from the CPU and GPU fans and heatsinks (if it's a desktop, open the case, if it's a laptop at the very least run a vacuum cleaner nozzle along the external air vents). You can also put the edge of a book under the back edge of your laptop so that it is raised off the desk at a slight angle, or purchase a laptop cooling pad (with USB powered fans) to sit the laptop on.
I neglected to mention that to use the new power management feature on R700 and newer hardware (other than APUs) requires installation of the latest AMD graphics microcode (ucode) files to /lib/firmware/radeon These are available at http://people.freedesktop.org/~agd5f/radeon_ucode/ Get the version ending in "smc". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/570589 Title: Lucid: Overheating due to no PM for ATI KMS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/570589/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
