Please attach anything vaguely relevant-looking from the system log (systemd Journal if you use systemd, or /var/log/syslog). The bug will probably be somewhere in the vicinity of logind, PAM, dbus-daemon, lightdm, X or XFCE, or possibly graphics drivers in the kernel (which have been known to lock up during fast-user-switching), but without looking at the log it's impossible to say which.
