Whenever I try to play a .mp4 video in VLC, X will crash. Display will keep displaying the last frame before the crash, but nothing will respond to mouse/keyboard or console commands. I’m not even able to switch to a VT (but I can ssh to my laptop just fine regardless). Sound will continue to work.
I also can’t seem to restart X/dm in any way (killall -9 Xorg, systemctl restart sddm), the only solution to this problem is reboot.
