I know that this is probably some close-sourced shenanigans, but can I push the limits of brightness below what GNOME sets? In Windows, I could go as low as I could, but this isn’t possible in GNOME anymore.
Typically their is some sort of low-level knob in /sys (try find /sys | grep backlight) which can be used to set it to any value. Be careful playing around though because 0 is often completely off and it can be hard to set it back. (Although a reboot should fix it if nothing tries to be clever and preserve it at shutdown.)
With my code, the lowest brightness setting should be closer to the minimum supported by the screen. There are some limitations with this because some screens become flickery at very low brightness levels. You might be able to circumvent the lower limit by using something other than the gnome settings daemon to set the brightness.
I hate that most Linux brightness controls assume that humans perceive brightness linearly for some reason. I don’t want a flash bang in dark surroundings when I forget to use the slider. I don’t want to press my brightness up key a thousand times or resort to the slider in bright surroundings.
Sounds great, and is very welcome! Please merge. Thank you. Do you guys have any idea why ddc/ci controls for brightness control of external screens are not yet implemented in any major De? It’s the same on windows, still not part of the Os. Third party tools available since ages.
But are there any DEs that make use of this and include setting screen brightness on external screens as easy as for laptops? Is it because each screen manufacturer implements altering brightness/contrast/etc. via ddcci differently?
I can see you’ve gotten some code review so I will just eagerly watch as this gets worked out and eventually merged.
I never had an issue with the backlight curve or lack thereof however a friend recently demoed a similar impl they put together for hyprland and it is a very nice change.
Looking forward to seeing it in the next Gnome release 🤞
