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.

DRM in this context (as mentioned by the other comment) is the interface between the userspace graphics drivers (Mesa, Nouveau, Nvidia etc.) and your graphics devices. It handles pretty much everything for rendering from displays to power management and memory synchronization, in a cooperative way that stops crashes due to race conditions, memory corruption etc.
