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?
If it’s wine, you could try installing ReShade
Yeah, do it at a hardware level.
Regardless of what kind of monitor you have, it should have gama/brightness adjustments.
I maxed what I can but still too dark. I mean maybe what I want is going to break the “intended look” of different games, but I don’t want them to be physically painful for me to play.
KDE has Gamma settings in the Display & Monitor area of system settings. So what you’re looking for is possible.
Only on X11, not on Wayland (as of 6.4).
Ah. Guess the steam deck must still run X11? That’s currently my primary computer, so I haven’t had to learn about/deal with X11 vs Wayland quite just yet.
If there’s just no system settings, you may try looking into mods, or learning how to manually edit the config file yourself?
It looks like for windows you can use opengl or a special launcher. I’m not sure how different it’ll be for you, but seems to be a common problem so someone has likely found a solution somewhere.
Not sure if Lemmy is big enough for someone to come tell you, but whenever you figure it out maybe edit you post with the fix so this stuff can start building up here.
For Deus Ex, try Zero Rando, it has a brightness boost option that works differently
Cool this was easy to install. I don’t see “Rando” menu option however, menu is same as before
Depends on the compositor.
- Hyprland has hyprsunset, you can increase the brightness without changing the color temperature using
hyprsunset -i --max_gamma 200% -g LEVEL. - For Wlroots compositors, you can try Gammastep. Wlroots seems to be the only compositor that implements a gamma correction protocol (though there is already an official color correction protocol in Wayland).
- Plasma on Wayland doesn’t have a gamma setting at the moment, but you can load ICC color profiles that might work. Also see this thread for another approach.
- GNOME and Cinnamon have this tool.
Yay, gammastep is just what I needed!
gammastep -O 8000K -g 1.5:1.5:1.5
- Hyprland has hyprsunset, you can increase the brightness without changing the color temperature using
