Hi,
This is still broken in build 19 (plex-desktop version 1.54.2) which causes segfault on launch on my Ubuntu 22.04 (running Gnome on Wayland) system.
DISABLE_WAYLAND must be set before the snap/command-chain/desktop-launch script executes, so setting it in Plex.sh is too late in the launch process.
I also note you’re running two different desktop-launch scripts - one that you are implicitly using from the gnome-3-38 extension (that is the one that supports disabling Wayland properly via the DISABLE_WAYLAND=1 variable) and the other that you’re adding separately (presumably via a part in your snapcraft.yaml). You should drop the latter one (in $SNAP/bin) in favour of relying on the one provided by the gnome extension. This will require dropping the bin/desktop-launch part of your command entry:
apps:
plex-desktop:
command: bin/desktop-launch $SNAP/Plex.sh
plugs:
- desktop
- desktop-legacy
- gsettings
- opengl
- wayland
- x11
- alsa
- audio-playback
- browser-support
- graphics-core20
- hardware-observe
- network
- network-bind
- screen-inhibit-control
command-chain:
- snap/command-chain/snapcraft-runner
- snap/command-chain/desktop-launch
(That is from meta/snap.yaml which is generated by snapcraft on build time, and isn’t exactly what you have in your snapcraft.yaml)
Edit: rewrite the post to be clearer.
