I haven’t tried weston-eglstream under nvidia proprietary in about two years, but it was working at the time. Just no acceleration when using X11 gtk2 apps like Steam. This has changed with a mesa patch from Adam Jackson that allows acceleration of X11 apps and nvidia blob.
With that recent mesa patch (WIP: GLX Delay (accelerated GLX for Xwayland with the NVIDIA driver) (!6429) · Merge requests · Mesa / mesa · GitLab), I wanted to give nvidia+wayland a shot again. When launching weston-eglstream 9.0.0 using 455.28 drivers, you are presented with a black screen, and have to switch tty to force close weston.
I made a post about this on the weston gitlab, and they redirected me to come here, as they said it’s a bug on your end.
He specifically mentions this line in the log.
“queueing pageflip failed: Device or resource busy”
Here is the log.
