ATI Radeon HD6970 (Cayman) power saving doesn't work with open source radeon driver
After googling and searching various forums for help didn't solve my problem, I now post here:
I'm running Kubuntu 12.04.01, Kernel 3.2, and using a Radeon 6970 (Cayman chip). Using two monitors side by side. The open source driver that comes with Ubuntu 12.04.01 is used. No xorg.conf exists.
I tried to set power save as per: http://askubuntu.com/questions/16207...aining-it-afte via:
echo profile > /sys/class/drm/card0/device/power_method
echo low > /sys/class/drm/card0/device/power_profile
shows no change wether I set low, mid, high or auto profile. Using dynpm as power_method has no effect either.
Any ideas what might cause this and how to proceed?
Thanks and best regards
