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.

This has turned out to be more tedious than I thought. I did the usual looking up tools to use, and found they use ddci, like ddcutil and ddccontrol, but they're very slow. Before setting them up, KDE's brightness slider did software brightness, now it does hardware brightness but now takes a whole moment with each brightness, I can't smoothly slide it back and forth like I can on laptops. I have a Dell G3233Q connected via USB For USB ports and DisplayPort.

brightnessctl is useful, can do percentage-wise. With some shell math you can also make buttons to increase and decrease it

brightnessctl doesn't work with Wayland

It does? I use it on KDE Wayland

Extra checked the name of the thing

I use it to change brightness via KDE Connect.

Huh. I should check again

It doesn't work for me on SwayWM, maybe KDE does something else under the hood?
