For the last year I’ve been playing lots of classic DOOM. DOOM has one feature that I started to appreciate ever since I learned about it, which is the ability to roll up brightness very high. This is what doom looks like when I play it:

I miss this thing in lots of other games. Recently I’ve been trying to get into Deus Ex (2000) via wine but it was so dark I couldn’t see shit. Maybe it’s my monitor that’s not very powerful or my environment that’s pretty bright by itself, but I feel just the simple ability to gamma correct any game or the whole desktop would solve this problem for me.

Do you know any such util that works on wayland?
