I neglected to say that to use the new DPM 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
If you have R700 or 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. Unlike the older dynpm method, the new DPM method 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. The currently under-development 3.13 upstream kernel enables DPM by default (without needing the radeon.dpm=1 boot parameter I mentioned above) for Radeon HD 4000 through Radeon HD 7000 series graphics processors but with some specific ASICs being excluded. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1058040 Title: fglrx-installer not working with AMD Radeon/Mobility Radeon HD 2000-4000 cards in Quantal Status in Release Notes for Ubuntu: Invalid Status in “fglrx-installer” package in Ubuntu: Won't Fix Bug description: Following the AMD decision to change to a new driver support model for Radeon™ HD 4000, HD 3000 and HD 2000 series cards for the legacy 12.6 driver as per http://support.amd.com/us/gpudownload/linux/legacy/Pages/legacy-radeon_linux.aspx , fglrx-installer installs non-working drivers for users of the cards: AMD Radeon HD 4000 Series AMD Radeon HD 3000 Series AMD Radeon HD 2000 Series AMD Radeon HD Series AGP AMD Mobility Radeon HD 4000 Series AMD Mobility Radeon HD 3000 Series AMD Mobility Radeon HD 2000 Series I suggest the addition of an fglrx-legacy package to install the AMD legacy drivers for users with older cards or patch the current code base for use with these cards. One of the outstanding issues for addressing this bug is AMD currently does not plan to support XServer 1.13 (for Ubuntu the package is xserver-xorg-core) for the legacy 12.6 driver, which Quantal uses: apt-cache policy xserver-xorg-core xserver-xorg-core: Installed: 2:1.13.0-0ubuntu6 Candidate: 2:1.13.0-0ubuntu6 Version table: *** 2:1.13.0-0ubuntu6 0 500 http://archive.ubuntu.com/ubuntu/ quantal/main i386 Packages 100 /var/lib/dpkg/status Output for fglrx 9.00 [1]: # lspci|grep VGA 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS780L [Radeon HD 3000] # modprobe fglrx FATAL: Error inserting fglrx (/lib/modules/3.5.0-15-generic/updates/dkms/fglrx.ko): No such device # dmesg|tail -n3 [ 6785.693869] [fglrx] Maximum main memory to use for locked dma buffers: 7132 MBytes.

WARNING !!!!!!! The following workaround has produced mixed results and left some users with temporarily broken systems. It is not recommended for production systems or novice users that are not comfortable with basic console/non-GUI recovery. USE AT OWN RISK. WORKAROUND: sudo add-apt-repository ppa:makson96/fglrx && sudo apt-get update && sudo apt-get -y upgrade && sudo apt-get -y install fglrx-legacy This workaround will downgrade X to 1.12 and install the AMD legacy fglrx 8.97 (Catalyst 12.6).
