Good point. I switched to tty2 (not sure if that's enough) and executed
DISPLAY=:0 rocketchat-desktop. Nothing happened, until I switched back
to tty7 (i3 desktop), when it immediately crashed and threw me back to
the lightdm login screen. Upon returning to tty2, the command did not
print any output but simply returned to the prompt.

Yes, it does core dumps to /var/lib/systemd/coredump/. What exactly do
you want to see?

Unfortunately yes, I need to use electron daily. However, I can't tell
exactly when I used an external screen for the last time, so I can only
tell for sure that it worked on July 2nd, or maybe Monday the 5th.
However, It seems likely that this issue is related to
https://gitlab.freedesktop.org/xorg/xserver/-/issues/1195 . Thanks Andy
