Although, it does allow for finer control of power/fans speeds. I bound a script to a keyboard shortcut that takes care of that for me. Now I just press Ctrl + 1 for lower power, Ctrl + 2 for medium, Ctrl + 3 for default, and Ctrl + 4 for high.
Code:
cat ~/.bin/gpu_power
#!/bin/bash
case "$1" in
low)
gksu 'echo low > /sys/class/drm/card0/device/power_profile' &&
notify-send --hint=int:transient:1 -t 2000 "Low GPU Power" "`cat /proc/dri/0/name`"
;;
mid)
gksu 'echo mid > /sys/class/drm/card0/device/power_profile' &&
notify-send --hint=int:transient:1 -t 2000 "Medium GPU Power" "`cat /proc/dri/0/name`"
;;
default)
gksu 'echo default > /sys/class/drm/card0/device/power_profile' &&
notify-send --hint=int:transient:1 -t 2000 "Default GPU Power" "`cat /proc/dri/0/name`"
;;
high)
gksu 'echo high > /sys/class/drm/card0/device/power_profile' &&
notify-send --hint=int:transient:1 -t 2000 "High GPU Power" "`cat /proc/dri/0/name`"
;;
esac
Then bind Ctrl + 1 to "gpu_power low" etc. Works well.
My HD 5770 works okay with the open driver. Not much worse than the catalyst proprietary one.
