Doc Text:
.X.org server no longer crashes during fast user switching Previously, the X.Org X11 `qxl` video driver did not emulate the leaving virtual terminal event on shutdown. Consequently, the X.Org display server terminated unexpectedly during fast user switching, and the current user session was terminated when switching a user. With this update, `qxl` has been fixed, and the X.org server no longer crashes during fast user switching.

Easy to reproduce. I confirm that patch from Ray does fix the issue [0], I'll follow up with him how it should be proposed upstream.
