From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I Made Screen Brightness Control on Gnome Much Better (gitlab.gnome.org)

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.

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.)
