Open a terminal, and copy the following

echo dynpm|sudo tee /sys/class/drm/card0/device/power_method

If you do not like it, you can return back by using

echo profile|sudo tee /sys/class/drm/card0/device/power_method

If you want to set at boot, type

sudo gedit /etc/rc.local

and add before "exit 0"

echo dynpm > /sys/class/drm/card0/device/power_method

This may reduce the performance
