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.

GNOME Sees Progress On Variable Refresh Rate Setting, Adding Battery Charge Control (www.phoronix.com)

As pointed out in This Week in GNOME, there's been some continued work on Variable Rate Refresh for the GNOME desktop. The VRR setting within GNOME Settings continues to be iterated on as the developers iron out how they'd like to present the Variable Rate Refresh setting for users. The developers have been discussing how to best present the option as to avoid confusion as well as how it makes the most technical sense as far as the option goes.

Why is that a ~~Gnome~~ WM thing and not a X/Wayland thing?

[–] SmoochyPit@beehaw.org 9 points 9 months ago (2 children)

I think the compositor, Mutter in Gnome’s case, has to explicitly request VRR from the display driver via the Wayland protocol. So it’s a bit of each.

via the Wayland protocol

There's no Wayland protocol involved, Mutter directly talks to the kernel

[–] SmoochyPit@beehaw.org 3 points 9 months ago (1 children)

Ah, I see, thank you for the correction. Does Wayland only encompass communication between clients and the server? I’ve seen some code calling the wlroots functions for requesting VRR and some of how the Nvidia open kernel modules respond. Is requesting VRR a part of Kernel Mode Setting, then?

Yes

Also yes

Thanks!

I believe it's actually a Mutter thing [1]

It is an X thing. Wayland is a protocol not a display server though, so for Wayland the Wayland compositor has to implement it (Mutter in this case)

[–] MonkderZweite@feddit.ch 1 points 9 months ago

Right, yeah. The thing i don't like about Wayland; duplication of code/work for every WM.
