It’s likely because it can’t access X11 or Wayland. To fix this, try editing the files in /home/your_username/.local/share/flatpak/overrides/ like I mentioned earlier. Specifically, look for the sockets line and make sure it includes wayland, x11, and x11-fallback like sockets=wayland;x11;x11-fallback;. This should help you launch flatpaks that need X11 access.






Yes, they are different because they are for different flatpak applications.
What’s in the files? Do they have a line called
sockets? Is that line set tox11orx11-fallback? Have you tried adding those options likesockets=wayland;x11;x11-fallback? I usually get an error saying I can’t connect to the display or that X is missing when I revoke access tox11orwayland. Or did you removex11from your system?
