I found a software repository there, enabled it in YaST, and I'm going to look
which packages seem relevant; but before I do:

There just was an update to systemd (in Leap42.1 Update-Test) so I had to
reboot. Usually I hit Esc as soon as the graphical "waiting" screen (green with
a square on its diagonal and three alternating blinking disks) appears, because
I prefer watching the boot log in the text console. This time I didn't, and
when the X11 login screen appeared, it had a visible mouse pointer.
