[Display] Fedora 41: Low contrast when setting Power Profile to "Power Save" and on battery

[questionlp]

With the release of Fedora 41, power-profiles-daemon has been replaced with tuned-ppd and the default powersave profile sets the value of /sys/class/drm/card1-eDP-1/amdgpu/panel_power_savings to 3 as before.

A new method of setting the value of panel_power_savings when changing power files needs to be created.

Using modified tuned profiles found in GokhanOfficial/tuned-ppd-config, a new, modified powersave profile can be created.

The new power profile that I created is called powersave-modified and the profile configuration is located at /etc/tuned/profiles/powersave-modified/tuned.conf, with the following contents:

[main]
include=powersave

[video]
panel_power_savings=0

The new profile inherits the settings from the default powersave profile, but changes the The main ppd.conf file needs to be updated so that the power-save profile points to the new powersave-modified profile. That can be done by modifying /etc/tuned/ppd.conf and change the power-save value under the profiles section from powersave to powersave-modified.

After both changes have been made, tuned must be restarted by running sudo systemctl restart tuned.

If you are already in "Power Save" mode, you may need to switch to a different mode and switch back for the changes to fully take effect.
