Comment # 1 on bug 960478 from Wolfgang Bauer

I can confirm this here, on 13.2 even.
But it only seems to happen with sddm as display manager.

Can you try something else, kdm or xdm e.g.?
You might have to install other ones (xdm should be installed by default) and
can set it in /etc/sysconfig/displaymanager afterwards (the DISPLAYMANAGER
variable).

If it's indeed just a problem with sddm, it might be a good idea to report it
upstream at https://github.com/sddm/sddm/issues ...
