My laptop has very high temps and I attempted to test the dynpm and mid profile to see if it will be any better ( according to this post: http://www.x.org/wiki/RadeonFeature )
However there is no /sys/class/drm/card0/device/ directory. on the other hand in my desktop there is. What might be wrong here?
My card is a Radeon HD 5470.
Thank you

| I guess you are missing firmware-linux-nonfree which includes the non-free firmware for amd/ati devices. The firmware is needed for 3d and video acceleration. |

firmware-linux-nonfree is installed. I reinstalled it anyway but nothing happens. The system is 64 bit kde-full Ημέρα.
OK Solved. I created radeon-kms.conf in /etc/modprobe.d/ with
options radeon modeset=1
Then
echo "profile" > /sys/class/drm/card0/device/power_method
echo "low" > /sys/class/drm/card0/device/power_profile
GPU temperature is lower than with fglrx and the screen is quite fast (with dynpm flickers).
