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.

Since nvidia drivers do not properly implement implicit sync, this protocol not existing is the root cause of flickering with nvidia graphics on Wayland. This MR being merged means that Wayland might finally be usable with nvidia graphics with the next driver release.

EDIT: Nvidia dev posted that support is planned in the 555 driver, with beta release planned for May 15: https://github.com/NVIDIA/egl-wayland/pull/104#issuecomment-2010292221

Questions from someone still on xmonad/x11, with 3 computers that have nvidia cards:

Do all nvidia cards have trouble in wayland currently, or is it just some subset?

Is it really unususable, or just really annoyingly flickery?

Would my card be usable now (without this merge) if I was using the nouveau driver?

Once this is merged, will all nvidia cards work in wayland? Or do we not really know yet.

Nouveau should have already been fine, this should fix the proprietary driver's issues. AFAIK this is a core issue of the proprietary driver, so should affect all cards.

I tried Wayland on my 16xx series GPU, Electron apps were only annoying, but games were unplayable. The desktop itself and Wayland native apps worked fine, though.

I only have experience with my current GPU (3070 ti) and only in Hyprland, but the only flickering I have is in steam windows, everything else works flawlessly on 535 driver. Still excited that it may be fixed soon!

The root cause of Nvidia flicker is Nvidia ecosystem being a total shitshow. This has nothing to do with drivers and how bad they are, or how Nvidia refuses to open source even the base of their desktop card drivers, or that the few tools they contribute to in in the OSS space to work around that are awful, or that the entire Linux environment for Nvidia is all about the datacenter (what an insane mess that is).

Good luck Nvidia+Linux fanboys.

Well, this is the root cause of this specific issue if you treat nvidia's part of the stack as some barely changable black box (which is what it is right now). It's not that I disagree open source drivers would be better, I just already own an nvidia GPU :/
