vlc film.mp4 VLC media player 3.0.3 Vetinari (revision 3.0.3-1-0-gc2bb759264) [000055d8f3d4b1d0] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface. Gdk-Message: vlc: Fatal IO error 2 (No such file or directory) on X server :50.
I got no idea how to debug this. any ideas? when doing the same with 'ssh -X', it works fine.
