Fixing color accuracy issue on Linux (integrated AMD GPU) on power saving/balanced preset

Issue

So after recent updates on Linux, laptops with integrated AMD Radeon graphics have a function to save monitor power consumption in exchange for color accuracy. This makes color on the screen looks like a mess when the system is on battery with power save or balanced preset due to adaptive backlight management in power-profiles-daemon (like Vari-Bright on Windows for example).

Solution

If you are using power-profiles-daemon then there are methods to disable it:

  1. By adding amdgpu.abmlevel=0 to the kernel command line. This will disable ABM value changes entirely.

  2. Use systemctl to create override for power-profiles-daemon.service:

    1

     $ sudo systemctl edit power-profiles-daemon.service

    Enter the following:

    1
2
3

     [Service]
 ExecStart=
 ExecStart=/usr/lib/power-profiles-daemon --block-action=amdgpu_panel_power

    And restart the service:

    1

     $ sudo systemctl restart power-profiles-daemon.service

  3. On Fedora with “Tuned”, you can edit tuned.conf file in /etc/tuned/profiles/[preset] folder. For example on powersave preset:

    1

     $ sudo vi /etc/tuned/profiles/powersave/tuned.conf

    In tuned.conf file, comment panel_power_savings like this:

    1
2
3

     [video]
 radeon_powersave=dpm-battery, auto
 # panel_power_savings=3

    Then restart the service:

    1

     $ sudo systemctl restart tuned.service
