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.
there is a ddcci dkms driver that exposes displays as Linux backlight devices. That integrates them into all DEs!
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?
yes, all of them. That’s how laptop screen brightness is controlled
