Comment # 1 on bug 1221507 from Fabian Vogt

> Well, tty1 of course belongs to agetty. In X11 mode SDDM is using setUpNewVt() which calls IOCTL VT_OPENQRY while in Wayland mode it starts with vt1 and checks whether there is logind session using it. Of course there is no logind session so it always assumes vt1 is available.

Yeah, that makes absolutely no sense. Can you file a report upstream instead
(if there isn't one already)?
