This is with the Signal App loaded via Flatpak.

The issue started with Signal being unable to attach a JPG to a
text message.  This started an interesting troubleshooting dialog
with ChatGPT which involved fiddling with flatpak override commands.
This ended ended with Signal failing to start with the following errors:

"/tmp/.X11-unix/X0 does not exist"

"bwrap: Permission denied"

She then recommended:

sudo rm -rf /tmp/.X11-unix
sudo mkdir -p /tmp/.X11-unix
sudo chown root:root /tmp/.X11-unix
sudo chmod 1777 /tmp/.X11-unix
reboot

That fixed it, it's been solid ever since.  This must have been a one-off
problem affecting only me or we would have heard more about it by now.

Regards,
Lew
