Explicit sync Wayland protocol has finally been merged! - eviltoast
linux-drm-syncobj-v1: new protocol (!90) · Merge requests · wayland / wayland-protocols · GitLab
gitlab.freedesktop.org
This is a new Linux explicit synchronization protocol based on DRM synchronization objects 1.

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

    For what it’s worth, I have only minor issues on wayland with nvidia, and all were fixable by changing some configuration option or something.

    Maybe my demands aren’t too heavy, but I do play games. I also use gentoo which makes fixing things easier.

      Maybe if your games are Wayland native or you’re still running the 535 driver? I saw fbdev=1 as a workaround, but that made things very jello-y.

        I think 535 is the only option for Wayland gaming right now, everything else is a flickery mess.
