Yes, I’m back.
Back, back, back… Back again.
My little pet project - making the Amulet Map Editor into a Flatpak - has hit another stumbling block.
On my Linux Mint testing system, it runs mostly fine (still trying to figure out WTF is going on with textures - different ticket though). However on my new EndeavourOS system, it does not even start.
Aside from one being Gnome and the other KDE, Mint is X11, Ubuntu based while Endeavour is Wayland, Arch based.
I had assumed (apparently incorrectly) that this config would allow the Flatpak to run on both X11 and Wayland:

runtime-version: '24.08'

According to the official docs, if I set - --socket=wayland and - --socket=fallback-x11 the host system’s Flatpak runner should first attempt to run using Wayland, then fall back to X11 if that doesn’t work, while choosing org.freedesktop.Platform should make the app flexible enough to run on both Gnome and KDE.
However, on Endeavour, when I run the flatpak, I get this error in the terminal:
Unable to access X display, is $DISPLAY set properly?
When I type echo $DISPLAY in Endeavour’s Konsole, I get :1 returned, so, what am I missing? Please tell me it’s not something super obvious.
