The open-source radeon driver is notorious for overheating laptops. Unfortunately, you cannot use fglrx/Catalyst on Ubuntu 12.10 or later for that GPU. Your best best is to stick with 12.04 and use the proprietary fglrx/Catalyst driver for now. Another option is using 12.10 and downgrading your Xserver using makson96 PPA, but that is a hack and may cause package management issues down the road (use at own risk): https://launchpad.net/~makson96/+archive/fglrx
Note that AMD is working on releasing better power management code/docs, but it's currently still under legal review: http://www.phoronix.com/scan.php?page=news_item&px=MTM0MjA -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1166916 Title: temperature overheating probably radeon To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lowlatency/+bug/1166916/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
