X server crash
Half a week ago I moved my OS to QEMU/KVM, enabled passthrough for GPU, mouse and keyboard, so far it's all worked fine. But today, while playing the game, the X server stopped displaying the picture and instead I see a terminal with a systemd boot log identical to vt1, and the sound looped. However, the Xorg process and all X server clients continue to run. My OS: Arch Linux X Server version: 1.21.1.8 DE: Xfce X server log:
