I believe you guys will want to:

  • run Firefox under wayland compositor with MOZ_ENABLE_WAYLAND=1

  • set widget.wayland-dmabuf-*.enabled to true and media.ffvpx.enabled to false, at about:config

As explained by FF dev Martin Stránský in his posts.

For screen sharing on swaywm, take a look at:

@GLaDTheresCake Maybe mach tries to use rustup when it is installed? We actually only use this PKGBUILD on a clean chroot (and rustup is not a makedepend), so it works fine. We make daily binary builds of this package at chaotic-aur.

However, if you suggest modifications to make the PKGBUILD more friendly for users not building on a clean chroot, I'd happily apply the modifications (as long as they are simple). I think most users won't want to build this package themselves, though (it takes around 1 hour to build in a 40-core machine).

The build is failing for me with the following error:

 0:05.82 DEBUG: Executing: `rustup which rustc`

You don't need that hack for the pipewire patch.

All you need to do is pull the correct Mercurial bookmark as the "beta" one reverts to the previous layout.


does it for me.

For the file dialog to work on swaywm, set widget.use-xdg-desktop-portal to false.

I have around 10Mb/s down and the download takes a long time (>20min). Could that be a timeout, or something like that?

Thanks for the fix @thotypous!

@jkbl, please post error messages using LANG=en_US.UTF-8:

configure pre-export export compile misc libs toolsTIER: configure pre-export export compile misc libs tools 4:11.23 make[3]: *** No rule to make target 'security/nss/lib/nss/nss_nss3/target', needed by 'netwerk/test/http3server/target'.  Stop.

It looks like an upstream problem with a testing component (we're already including nss-hg as dependency). Also, seems to be failing since 27/03.

Ping me in a week if it isn't fixed yet. Till then, you can always find my latest successful daily build here.

Hi @Fandekasp. For that to work, you'll need to rebuild/update nss-hg.

I'll be studying to add it with a condition in the dependencies list. It would be better cause you would know when an update is needed before start building. But It would depend on me changing it manually on every change.

You can also catch up with my daily builds in Chaotic-AUR.
