VLC crashes systemd

Despite using mostly mpv media player, days ago, I was playing a DVD-Video ISO image with VLC and, all of a sudden, systemd crashed again, for the same reason.

Until then, aside kernel panics, I had never had a systemd crash, let alone two crashes in just a matter of days.

Re: VLC crashes systemd

That's not systemd crashing, that's X.

Re: VLC crashes systemd

On my machine vlc 3.0.4-7 crashes due to a problem with libdvbpsi. Downgrade to 3.0.4-6 fixes the problem.

Re: VLC crashes systemd

@bt, vlc crashes are not the same as Xorg server crashes…

@damnbug (Do you really want to be called like this ;-)
Optimus system?
Please post "lspci" output and your xorg log.

Then why does it kill internet connections, screen, even irssi?

Re: VLC crashes systemd

Everything that relies on the shell server will go down. If you're running screen & irssi in shells under the X11 session / in X11 VTEs, they'll die as well.
On top of that the backtrace you provided explicitly states "systemd-coredump[12297]: Process 460 (Xorg) of user 0 dumped core" so there's really no question about what happens.

Please answer post #4 and provide the requested output if you want this to go anywhere.
You may also paste a *complete* journal of the boot if you feel there may actually being previous issues leading to the Xorg crash as a mere follow-up, but as of now, you've only provided evidence of an Xorg crash.
