Description

Please read these instructions and remove unnecessary text.

• I have included the night light functionality in Hyde.
• I like the night light because it is perfect for my eyes to work for multiple hours on my system. However, Hyde does not support it, so I included it using wl-gammarelay-rs.
• wl-gammarelay-rs needs to be installed to use the night light.## Type of change

Did you check it with hyprctl dispatch dpms off and does it still save night light after dpms is back on? Other wayland utils like gammastep does not and need to be restarted.
