I am using nixpkgs from your PR branch, and I have added this module to my system. I am running from /run/system/current-sw/bin/sway to avoid using the sway from home-manager.
Got it working, I needed to add hardware.nvidia.modesetting.enable = true;
Sway/wlroots logging is glitchy and prints lines on top of each other, I didn’t see the error about KMS until randomly running it for the 15th time.
I can use sway now with gtx 1080. All of the following fail with getting EGL display.
glmark2-es2
env SDL_VIDEODRIVER=wayland xonotic-sdl
webgl in Firefox.
Chromium seems to work, but I am not sure how to test that. Xonotic and CS:GO start in Xwayland, but with very bad performance. It seems this is expected with Xwayland, according to the wlroots-eglstreams readme.
fwiw, it seems like the egl-wayland that nvidia builds with will be updated soon (ref), maybe closing this gap again? (But also, there’s apparently some regressions for certain users related to the very latest egl-wayland [that isn’t even merged yet] (ref))
I tried egl-wayland 1.1.8 and I have some problems with that, like firefox not starting. I saw here that egl-wayland 1.1.8 needs the unreleased nvidia driver to work.
Granted, it’s day 1, but the wlroots-eglstreams patched Sway with stable nvidia had much more consistent, better performance.
But it is working. Running HEAD of sway, with HEAD of regular wlroots, on an RTX 3080 with jonringer’s nvidia_x11_beta PR.
I am currently experimenting with a PR to add an option for adding a “custom” egl-wayland package so that it will be easy for users to play with egl-wayland from nvidia, the “current” stable, and the next stable release, all of which seem to act differently.
Hi @colemickens I saw that is possible to use the GBM_BACKENDS_PATH env var to indicates to Mesa where to load the GBM backend:

But I’m having problems with Xwayland, anything that uses OpenGL is not working in Xwayland. I think that is because Gnome-shell uses Eglstream and Xwayland tries to use GBM.
For anyone trying to get xwayland working with GBM: make sure to try nixos-unstable (works for me on 5f0194220f2402b06f7f79bba6351895facb5acb) rather than the nixpkgs-wayland overlay; something seems to have broken in Sway or wlroots such that it’s failing to register the wl_drm capability in the latest repo versions:

Heh, I just meant what application? I’m kind of bad at this GL stuff, I’m not even sure what the basics are for validating every single piece underneath X11/Wayland, etc. I have another thing or two to try, but not even sure if I’m checking the right thing!
(edit: or is that just sway itself starting up and falling back to SW rendering? strange that I’m not seeing that if so)
