Summary : Set contrast, brightness and gamma for wayland compositors
URL : https://github.com/mischw/wl-gammactl
License : MIT
Description :
: Small GTK GUI application to set contrast, brightness and gamma for
: wayland compositors which support the wlr-gamma-control protocol
: extension. Basically this is the example from here:
: https://github.com/swaywm/wlroots/blob/master/examples/gamma-control.c
: with a nice little GTK GUI slapped on to it. You can set contrast,
: brightness and gamma using sliders and reset back to default values.
:
: This was made to make the process of calibrating your monitor a bit
: easier, since wayland support for color profiles is not yet
: implemented. When you are satisfied with your settings, copy the given
: command line and execute it at startup to make the settings load at
: apply on every boot.
:
: Keep in mind that it uses the same protocol extension as the
: redshift fork
: https://aur.archlinux.org/packages/redshift-wlr-gamma-control/
:
: wl-gammactl will kick out any running redshift instance and fail to
: start up. On second run it should work as expected. So unfortunately
: only one can run at a time (?) for now.
