I am trying to follow this tutorial: https://gist.github.com/Francesco149/0302fbb5e056f3339ae17d3c13257929
- The first step is to run
sudo suto switch to root. Done that.
The second step is to run
echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level
So I ran it, and here's what I got:
bash: /sys/class/drm/card0/device/power_dpm_force_performance_level: Permission denied
Permission denied?! How is that and I am the root user? How is it possible?
I have no idea of the inputs you would need from me, so please tell me and I will reply to you asap.
Here is the output of
echo high | sudo tee /sys/class/drm/card0/device/power_dpm_force_performance_level (running as
tee: /sys/class/drm/card0/device/power_dpm_force_performance_level: Permission denied high
