A command-line tool that lets you change gamma in GNOME and Cinnamon (with Wayland). You can also adjust contrast and brightness. It works by creating a color profile with the VCGT table, so that changes are persistent and don't interfere with other settings like night light.
That's because there are no python dependencies :D
However, since this tool interacts with the system, some system dependencies might be needed, but try to run it first, I'll try to help find what's missing.
Hi, wanted to check out this tool but could not find a requirements.txt for installing dependencies.
