Description vaidas.boqsc 2019-05-24 07:35:28 UTC 
I tried to change power profile of a GPU to a lower one, so that laptop won't overheat so quickly.

I found this method on the internet and various documentations:
 
echo low | sudo tee /sys/class/drm/card0/device/power_profile
tee: /sys/class/drm/card0/device/power_profile: Invalid argument

However this method never worked - Invalid argument show up no matter what value I try to give the power_profile


Even giving the already existing "default" value to the power_profile leads to "invalid argument" error.

echo default | sudo tee /sys/class/drm/card0/device/power_profile
tee: /sys/class/drm/card0/device/power_profile: Invalid argument

I would like to know why this is happening.

Please attach your dmesg output and xorg log (if using X).

xorg log
Comment 4 Michel Dänzer 2019-06-06 08:26:34 UTC 
The attached dmesg output shows no sign of the radeon driver being loaded. The attached Xorg log file is from a system with Intel and Nvidia GPUs, no Radeon. Please attach the information corresponding to the reported problem.

Previous xorg log was a mistake, of a different machine.

The function I used to gather xorg log: 
vaidas@vaidas-SATELLITE-L855:~/Desktop$ cat  ~/.local/share/xorg/Xorg.0.log > Xorg.0.log
