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.

Yeah the driver supporting LEDs and exposing them should be installed. The exposed LEDs can be found in
/sys/class/leds/<device>/multi_[index|intensity], See Linux kernel documentation for details: LED handling under Linux and Multicolor LED handling under LinuxI'm not familiar with KDE's new feature yet, but if it only supports sysfs LEDs then it won't control 99% of keyboards. Few RGB keyboards have drivers that expose this interface. Most RGB keyboards are controlled from userspace on their official software on Windows, and that's also what most Linux projects that control RGB devices including my OpenRGB project do. I wonder if it would be possible to write an OpenRGB plugin/script that exposes a virtual /sys/class/leds/openrgb device that KDE could talk to, then translate that into OpenRGB calls to set the color on all available devices. It doesn't sound too difficult.
