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.

Other than games, what are the benefits of variable refresh rate?
Adjusting the refresh rate to the performance of the desktop is one.
I also heard it would make it easier to manage multiple monitors sporting different refresh rates, although I haven't had issues with that personally.
That's the definition, isn't it? Why is this better than a fixed refresh rate? Can the monitor scale the rate down to consume less power or something?
I heard that too and got similarly confused. I work with two monitors with different refresh rates (75 and 60) on Mint and it seems fine. Is X downgrading my 75 Hz monitor to 60 silently? I don't know how to check that.
In theory, yes. However, I have never seen it used that way. The only widely used applications for VRR are games and video playback.
Would be interesting to do some power measurements though.
Yes, X does not support different refresh rates. Wayland does.
