Bug#852690: sddm: circumventable with 0.14

["Christopher Huhn, GSI" <C.Huhn@gsi.de>]

Package: sddm
Followup-For: Bug #852690

Hi again,

with SDDM from experimental and 'EnableAvatars=false' SDDM starts up so that logins are possible.

With 0.13 the problem becomes even worse after a while: 
due to the huge amount of NFS mounts systemctl is no longer able to talk to systemd ('Connection timed out').
Even shutdown and reboot won't work any more. It is ridiculous.

This bug will affect all multi-user setups in similar cluster environments.
Please don't ship stretch with version 0.13 of SDDM.

Even with avatars turned on, SDDM should not load more face icons than it can display.
IMHO the browsing mode does not make sense for more than 15-20 login accounts anyhow.
Maybe it should be automatically turned off if the amount of login accounts is 
above some threshold?

Kind regards,
	Christopher
