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.

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.
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
