gnome-gamma-tool

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. (by zb3)

  • Tune your low quality display by reducing gamma

    I purchased a mint condition T490 recently but I found the display to be inferior compared to the touchscreen of my T460. Both have 45% NTSC coverage but the T460 is pretty good in my opinion while I thought the T490 is too bright, almost washed out (it came with the standard FHD IPS AUO panel). Then I realized that it's actually the gamma that is too much for my liking and this is something that you can control from software. So I set it to 90% with this tool and voilá the display now has more contrast and looks much better to me. Difference is pretty big actually, it went from I want to replace it to it's perfectly fine in a blink of an eye. Absolutely recommended!

    However, this does not work in Wayland since it obviously belongs to the X Window System. I started searching the web for a possible solution and found wl-gammactl, which is a GUI for wlroots (https://github.com/mischw/wl-gammactl) and the gnome-gamma-tool (https://github.com/zb3/gnome-gamma-tool), but neither of them seemed to work because of missing dependencies, which can't be installed or invalid version numbers of required packages (e.g. found 1.20 but need: '>=1.23'). When attempting to build the gnome-gamma-tool, the following error message appears (despite Colord being installed):
