Hyperlinks to scripts? I’ve been wanting to do something similar for ages for those few occasions where ambient sunlight really wanted me moving to something that wasn’t a dark. It seemed like quite a bit of work since, like you, more often than not, I’m not in that sort of environment.

I have no nice release but on hyprland, I use the following to increase /sys/class/backlight/intel_backlight/brightness by steps of +- 200 units that I calibrated with my eyeballs and /sys/class/backlight/intel_backlight/max_brightness: binde = , XF86MonBrightnessDown, exec, $HOME/.config/hypr/changebrightness.sh - 200 binde = , XF86MonBrightnessUp, exec, $HOME/.config/hypr/changebrightness.sh + 200 The script is just reading /sys/class/backlight/intel_backlight/brightness and writing back the same value +- 200 The most important is what plays with that: color inversion, red shift, contrast increase, so install gammarelay-rs and wl-gammactl then do key mappings. The contrast increase is a nice feature to avoid trimming low contrast element (ex: light key text on a grey background), before moving to use exclusively red on black ("submarine" night mode) # alt= dark red nightmode # WARNING conflict betweel wl-gammarelay-rs and wl-gammactl: before using one, must killall the other first # So unconditionally kill the other before running commands bind = ALT,Print, exec, killall wl-gammactl bind = ALT,Print, exec, killall wl-gammarelay-rs || ( wl-gammarelay-rs & busctl --user -- set-property rs.wl-gammarelay / rs.wl.gammarelay Temperature q 1000 ) # Control= increase contrast for OLED dark bind = CONTROL,Print, exec, killall wl-gammarelay-rs bind = CONTROL,Print, exec, killall wl-gammactl || GTK_THEME=Adwaita-amoled-dark-Fix wl-gammactl -c 2.500 -b 0.700 -g 1.000 # Shift= invert bind = SHIFT,Print, exec, killall wl-gammarelay-rs bind = SHIFT,Print, exec, killall wl-gammactl || GTK_THEME=Adwaita-amoled-dark-Fix wl-gammactl -c -1.000 -b 2.000 -g 1.000 # Win= brightness menu bind = WIN,Print, exec, killall wl-gammarelay-rs bind = WIN,Print, exec, killall wl-gammactl || GTK_THEME=Adwaita-amoled-dark-Fix wl-gammactl > I’ve been wanting to do something similar for ages for those few occasions where ambient sunlight really wanted me moving to something that wasn’t a dark. If it's a rare occasion, you must use a dark theme by default, so I would do - first Ctrl+Printscreen to try to increase the constrast of your back theme: it's rare and counterintuitive, but if you have no reflections on the screen, it can help in the sun - if it's not enough cancel it by another Ctrl+PrintScreen, then Shift+Printscreen to toggle the inverted mode - then Fn F5 (which causes XF86MonBrightnessDown on by thinkpad) to reduce the brightness until you like it If works best if you have OS-wide theme toggle. I use 2 terminals with different themes because unlike on Windows Terminal, on Linux the hot toggles of colors themes for Terminals isn't working so well. If you have a brightness sensor (often in the keyboard, for color calibration on thinkpads, or in the webcam housing for balance adjustement), you could do much better: record in a sqlite database the timestamps, the brightness value, and your actions (ex: reducing lightness +400) After a few days of collecting metrics, you should be able to calibrate a default reponse that would change with your habits: imagine pressing a key and reproducing your modal reponse to this kind of ambiant brightness (this theme, that brightness, this color filter...)

  Thanks. I can think about some of these topics but I can’t use hyprland because there is no color management in Wayland :\

    I don't know what you mean by color management - is it the calibration of the display with xrite/argyll? For ICC profiles colormgr can help: https://wiki.archlinux.org/title/ICC_profiles#Wayland https://wiki.archlinux.org/title/ICC_profiles#Wayland If you just need basic brightness, contrast and gamma, wl-gammactl should do that: https://github.com/mischw/wl-gammactl https://github.com/mischw/wl-gammactl BTW Hyprland is not required, it's just the most practical way to have shortcuts key mappings in Wayland
