xgamma and xrandr only work in xorg, is there a command or program to adjust the brightness and contrast in gnome wayland ?
My computer is a desktop and monitor is a 2K LCD monitor, without backlight feature.
Changing the color temperature may temporarily solve my issue.
This is a temporary solution, not a final one.
By default, Windows10 has very good brightness and colors, while Fedora32 colors look pale and the white is especially harsh.
Guess the amdgpu open source driver still not good enough for Radeon RX 480.
