Better power management for AMD/ATI Radeon R600 and newer hardware is finally available in the upstream 3.11 linux kernel. The first release candidate (3.11-rc1) of the 3.11 kernel is available at http://kernel.ubuntu.com/~kernel-ppa/mainline/ and instructions on how to install and uninstall it are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds
To use this power management for the AMD/ATI Radeon you will need to select it at boot by adding radeon.dpm=1 to your GRUB kernel boot options as described at https://help.ubuntu.com/community/Grub2/Troubleshooting#Editing_the_GRUB_2_Menu_During_Boot See the blog post at http://www.botchco.com/agd5f/?p=57 for further information. Unlike the older dynpm method, the new DPM mehod works with multiple monitors and there shouldn't be any flickering as the performance level changes are handled by dedicated hardware rather than the driver. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1042492 Title: Open source radeon driver causes laptop to heat up / run fan non-stop Status in “xserver-xorg-video-ati” package in Ubuntu: Triaged Bug description: Whenever I use the open source radeon driver on my laptop the machine heats up dramatically and as a result needs to run the fan non-stop. This in turn causes the battery to drain quite quickly and makes the machine almost unusable due to the heat it gives off. When I install the proprietary driver my laptop does not have this problem. I am currently experiencing this problem in 12.10 Alpha 3 but it has been an issue for a number of releases now.
