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.

While some of us had it turned on for some time, some didn't. Looks like it is fully stable now.

Yey! Test it by starting intel_gpu_top and than playing video in firefox, if row "Video" goes over 0.0% it is working!

Of course, you need second monitor, it goes down to 0 if video is not visible, since Firefox is not rendering it.

You don't need a second monitor, if you open your terminal with intel_gpu_top running and firefox side by side.

Makes sense, thank you. I forgot that is an option, since I am using everything in full screen on tilling wm.
