Gnome-shell-extension-Radeon-Power-Profile-Manager Уменьшаем нагрев Radeon на постоянной основе chmod a+w /sys/class/drm/card0/device/power_profile sudo nano /etc/rc.local

echo low > /sys/class/drm/card0/device/power_profile

Памятка: To use this extension you need:

A Radeon card that supports power profiles - r1xx and up;
To be running the open source drivers;
Make sure that /sys/class/drm/card0/device/power_method is set to profile;
Set the permissions of /sys/class/drm/card0/device/power_profile to be writable by your user (by default only root can change these values);
chmod a+w /sys/class/drm/card0/device/power_profile will work, but feel free to use any other method;
to make the changes permanent don't forget to add the chmod line to your rc.local

or equivalent in your distro (If your /etc/rc.local

contains an exit 0 line, then the chmod line has to be placed before it);
if you are using systemd, you can create /etc/tmpfiles.d/radeon-power-profile.conf with the following line:
w /sys/class/drm/card0/device/power_profile 0666 - - - mid;
this will change the permissions of power_profile so that any user can change the profile;
If you do not do this, the extension will attempt to use polkit and ask for your password every time you change the profile.
