Anyone here struggle with trying to adjust brightness on Gnome in low light? At the low end, the steps are way too far apart, and at high brightness they’re almost imperceptible. Every other operating system uses a brightness curve that better matches human perception.
I’ve improved the brightness control of the Gnome settings daemon, using a bezier curve based brightness curve. I’ve also written all the appropriate tests which it passes. With this implementation, the change in brightness between each step should be perceptually identical, providing more nuance at low brightness and faster control at high brightness.
Would you all like to see this become a part of Gnome? The MR is about 4 weeks old now and the maintainers haven’t looked at it yet so I’m looking to gauge public interest and see if users want to see it merged.
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(tryfind /sys | grep backlight) which can be used to set it to any value. Be careful playing around though because0is 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.
