distrobox + wayland + XKBNotFound (/usr/share/X11/xkb missing)

[softmoth]

Hi!

I have on a Bluefin (Fedora Silverblue derivative) aurora-dx-nvidia:stable Linux host running on a Lenovo Legion 5 Pro 16ACH6H laptop (Nvidia mobile GeForce RTX 3070) with KDE Plasma 6.1.2 on Wayland.

I create a Wolfi container from the following distrobox.ini:

[rust]
image=cgr.dev/chainguard/rust:latest-dev
nvidia=true
pull=true
additional_packages="neovim rust-analyzer"

and the command distrobox assemble create -n rust && distrobox enter rust.

Once in the container, I want to work on a Rust project using the Bevy game engine. To start, I get the basic template from the bevy project:

git clone https://github.com/TheBevyFlock/bevy_quickstart.git
sudo apk add wayland-dev alsa-lib-dev systemd-dev
cargo build --release

The project builds OK, but trying to run it results in an error saying xkbcommon: ERROR: failed to add default include path /usr/share/X11/xkb; "XKBNotFound":

I'm able to get past this issue if I copy the missing directory from the host into the container:

distrobox-host-exec tar -C /usr/share/X11 -cf- xkb | sudo tar -C /usr/share/X11/ -xvf -

(I then run into a problem with ALSA not finding a sound card, and with WaylandSurface failed: ERROR_OUT_OF_HOST_MEMORY, but I haven't tried to work through that quite yet.)

So my question after all this is, why is /usr/share/X11/xkb not populated, and what packages do I need to add to get them? I tried adding the following, but it didn't help:

sudo apk add libxkb
sudo apk add libxkbcommon  
sudo apk add libxkbcommon-static
sudo apk add libxkbfile 
sudo apk add libxkbfile-dev
sudo apk add libxcb
sudo apk add libxcb-dev
sudo apk add wayland
sudo apk add wayland-dev
sudo apk add wayland-libs-cursor
sudo apk add wayland-libs-egl
sudo apk add wayland-libs-server

I found a similar report at neovide/neovide#2293 but it appears to have just been a missing dependency on libxkbcommon. I've tried adding that package in Wolfi and it doesn't seem to help.

Thanks for any help!
