This shell script uses kdialog to allow Radeon GPU power profile change graphicaly.

Dependencies :
- kdialog
- sudo

The user must be allowed to write the sys file. I do it through the following /etc/tmpfiles.d/radeon.conf file :
w /sys/class/drm/card0/device/power_profile 0775 - live - low
w /sys/class/drm/card0/device/power_method 0775 - live - profile
