Better power management (than that mentioned in comment #25) 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 On R700 and newer hardware (other than APUs) you will also need to install 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". R700 basically means Radeon HD 4000 series and newer. However note that according to Wikipedia and http://xorg.freedesktop.org/wiki/RadeonFeature/#index5h2 the Mobility Radeon HD 4225/4250 is a RV620 chip, so anyone with one of those shouldn't need the updated firmware files. 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/373669 Title: [RV620] No power management with ati driver Status in X.org XServer - ATI gfx chipset driver: Fix Released Status in “xserver-xorg-video-ati” package in Ubuntu: Fix Released Bug description: Binary package hint: xserver-xorg-video-ati With my hardware - Mobility Radeon 3400 (RV620) - I have no power management with the opensource drivers, both ati and radeonhd.
