I’ve got a brand new Ubuntu 22.04 VM I just built on ESXi 7. I’ve gone through the steps to install flatpak. Next I followed the steps for installing plexamp shown here: [Flathub—An app store and build service for Linux](https://flathub.org/apps/details/com.plexamp.Plexamp) Everything goes fine until the final command, when I get a core dump. Any ideas? root@plexamp:/home/plexamp# flatpak run com.plexamp.Plexamp Passing the following arguments to Electron: --enable-gpu-rasterization --enable-zero-copy --enable-gpu-compositing --enable-native-gpu-memory-buffers --enable-oop-rasterization --enable-features=UseSkiaRenderer [3 zypak-helper] Failed to connect to session bus: [org.freedesktop.DBus.Error.NotSupported] Using X11 for dbus-daemon autolaunch was disabled at compile time, set your DBUS\_SESSION\_BUS\_ADDRESS instead [3 zypak-helper] src/helper/main.cc:40(DetermineZygoteStrategy): Assertion failed: bus /app/bin/startplexamp: line 22: 3 Aborted (core dumped) zypak-wrapper /app/bin/plexamp/plexamp “${FLAGS[@]}” “$@” root@plexamp:/home/plexamp# ---

Hi, fellow Wayland user 🙂 I’ve filed an issue at [Crash with "GPU process (undefined) crashed (133)" in Wayland session · Issue #60 · flathub/com.plexamp.Plexamp · GitHub](https://github.com/flathub/com.plexamp.Plexamp/issues/60), you’re welcome to chime in, maybe this would help it gain some traction. /cc @aubrey.wodonga ---
