Following change is included: "container-guest-tools: Allow passwordless pkexec" (https://chromium.googlesource.com/chromiumos/containers/cros-container-guest-tools/+/939ae3eb75e983d5c3994606e38df79f18ea28fb%5E%21)

Yes that solved the issue for me. Thank you for making the change.

OK, got it. I updated PKGBUILD to include setting up LIBGL_DRIVERS_PATH for sommelier and sommelier-x. I am not patching units, just added new line to override configuration - this is more clean way making it.

On my Pixelbook GPU acceleration works fine out-of-the-box with up-to-date arch and 77 beta ChromeOS version. Updated PKGBUILD works fine too.

Please try and confirm it resolves the issue for you.

The errors I was seeing were previously mentioned by rawkode where sommelier would fail to run with MESA-LOADER errors failing to find the dri drivers and well as the ones mentioned by mrln getting gpu acceleration to work.

Both of them fixed the issue by overwriting the dri drivers in /usr/lib/dri with those found in /opt/google/cros-containers/lib to allow sommelier to start and then switch back to the original libs to allow the bundles apps to work correctly.

By updating the sommelier service file to use /opt/google/cros-containers/lib for it's dri divers directly we no longer need to shuffle around these files.

Note: I'm not sure how this was working by default on your pixelbook without any of these changes but this was required to get sommelier and gpu acceleration to work on my HP chromebook X2.

Interesting, thanks for sharing - I will incorporate this to the PKBUILD! Can you provide more information about the errors you are mentioning?

In order to get sommelier to run correctly without any MESA-LOADER errors and get GPU support working I added the following lines to /usr/lib/systemd/user/{sommelier@.service,sommelier-x@.service}

Environment="LIBGL_DRIVERS_PATH=/opt/google/cros-containers/lib"

Last update implements more ChromeOS keys binding inside Crostini as described here: https://www.reddit.com/r/Crostini/wiki/enable-chrome-shortcuts-in-linux-apps

Looks like I am getting GPU working out-of-the-box on my Pixelbook with latest version of this package and in latest dev version (77.0.3865.18) with gpu flag set to on. Getting virgl as driver now. Finally I can watch H265 video on using mpv with GPU acceleration!

Thanks, @mrln! I will check this out on my Pixelbook and will incorporate into this package if it works.

I temporarily got gpu running using a hacky trick. I'm using a HP X360 chromebook, Chrome OS 76.0.3809.38 and crostini archlinux container. The way i got it working:

Backup virtio_gpu_dri and symlink the google virtio_gpu_dri

mv /usr/lib/dri/virtio_gpu_dri.so /usr/lib/dri/virtio_gpu_dri.so.orig
ln -s /opt/google/cros-containers/lib/virtio_gpu_dri.so /usr/lib/dri/virtio_gpu_dri.so

Enable gpu

Open cros shell using Ctrl+alt+t

vmc stop termina
vmc start --enable-gpu termina

Open linux terminal Run glxinfo -B, it segfaults with unknown architecture error.

Restore backup virtio_gpu_dri overwriting symlink.

mv /usr/lib/dri/virtio_gpu_dri.so.orig /usr/lib/dri/virtio_gpu_dri.so

Now glxinfo -B show virgil as driver. Steam games work. Oh, and somewhere during testing i had to install libc++ from aur because "LIBGL_DEBUG=verbose glxinfo" was complaining about it missing.
