Small tool to change your gamma; not great, but source is easy to modify. This was designed to be mostly useful for keybinds in tiling window managers, for example i put this in my i3 config: bindsym $mod+g mode "gamma" mode "gamma" { bindsym Left exec --no-startup-id gamma -5 bindsym Right exec --no-startup-id gamma 5 bindsym Down exec --no-startup-id gamma -1 bindsym Up exec --no-startup-id gamma 1 bindsym r exec --no-startup-id bash -c 'xrandr --output HDMI-0 --gamma 1 && rm /tmp/gamma' bindsym Escape mode "default" }
