I just followed the recommendations on: http://www.x.org/wiki/RadeonFeature and did: $ sudo -c sh 'echo "auto" > /sys/class/drm/card0/device/power_profile' This solution, if it doesn't trigger problems for anyone, should be made either the default or easily configurable through some file in /etc. --- Architecture: i386 DistUpgraded: Fresh install DistroCodename: natty DistroRelease: Ubuntu 11.04 DistroVariant: ubuntu InstallationMedia: Kubuntu 11.04 "Natty Narwhal" - Alpha i386 (20110202) Package: xserver-xorg-video-ati 1:6.14.0-0ubuntu4 [modified: usr/lib/xorg/modules/drivers/ati_drv.so] PackageArchitecture: i386 ProcEnviron: LANGUAGE= PATH=(custom, no user) LANG=en_GB.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 2.6.38-8.42-generic 2.6.38.2 Tags: natty ubuntu Uname: Linux 2.6.38-8-generic i686 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: version.compiz: compiz N/A version.libdrm2: libdrm2 2.4.23-1ubuntu6 version.libgl1-mesa-dri: libgl1-mesa-dri 7.10.2-0ubuntu2 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 7.10.2-0ubuntu2 version.xserver-xorg: xserver-xorg 1:7.6+4ubuntu3 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:6.14.0-0ubuntu4 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.14.0-4ubuntu7 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:0.0.16+git20110107+b795ca6e-0ubuntu7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/771963/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
