I doubt this. The Xserver dies however when the systemd-logind which has opened
a device is gone. The Xserver starts if systemd-logind fails on all instances
(or all but the last) as then the fallback is used all the time (or in the
latter case systemd-logind isn't killed on a consecutive device open
operation).

Will see if I can attack gdb.
