[SOLVED] Hardware Acceleration on GNOME Wayland

Hi all,

I have recently been trying out GNOME on Wayland but seem to been running into issues with hardware video acceleration. Firefox/Alacritty stutters frequently, videos are unwatchable.

After doing some searching I came across this bug report which is likely the cause.

Anything I can do or just switch back to Xorg and wait for a fix?

The error:

~ $ vainfo
Xlib:  extension "NV-GLX" missing on display ":1".
Xlib:  extension "NV-GLX" missing on display ":1".
zsh: floating point exception (core dumped)  vainfo

Also seeing this:

Re: [SOLVED] Hardware Acceleration on GNOME Wayland

The last comment on the bug report you quote claims it is fixed by the current nvidia 510 beta. You can try that via the AUR already.

Wasn't aware it was available, have given it a try and it has removed the NvKmsKapiMemory errors but vainfo is still returning the same error. Perhaps they were unrelated?

Re: [SOLVED] Hardware Acceleration on GNOME Wayland

I don't think the warning is the cause. That one probably occurs due to the /var/run symlink.
Have a read at the second link to gnome mutter bug mentioned in: https://wiki.archlinux.org/title/Wayland#Requirements
The users there report choked firefox video streams as well.

Re: [SOLVED] Hardware Acceleration on GNOME Wayland

UPDATE:

vainfo will never work under Wayland as it uses xlib. Hindsight is a wonderful thing.

I saw someone suggest trying Firefox nightly on Wayland and it works. So the issue lies with Firefox.

Re: [SOLVED] Hardware Acceleration on GNOME Wayland

Fixed in firefox 96.x by adding:

env MOZ_ENABLE_WAYLAND=1

to firefox.desktop as described here.
