Description Todor 2012-06-24 01:17:54 UTC 
I'm using open source radeon driver I can't manage to set the power_profile on boot - I have to do it manually after login
I have added in /etc/rc.local

echo profile > /sys/class/drm/card0/device/power_method
echo low > /sys/class/drm/card0/device/power_profile
exit 0

http://www.overclock.net/t/731469/how-to-power-saving-with-the-radeon-driver

and try to boot a script as a service - doesn't work

Any Idea how to set a low/mid profile to the power_profile at boot ?

Doing it via rc.local or something similar is the correct way to do it.
