[Bug 1584604] Re: Slow login to kde5 waiting on networkmanager

[Martin]

Hi,

I have the same problems (Kubuntu 16.10, SDDM, network-manager, notebook
with Skylake Core-i3-6100U with external HDMI-Monitor both 1920x1080px).
I did some experiments to find the cause:

1. create a new user test2
2. reboot
3. login as test2
4. --> Fast login to the Plasma --> Since network-manager and plasma-applet is running this does not seem to cause the 30s delay

Now I tried out some adjustments in the system setting like
a) Plasma theme
b) start with a empty session
c) show no options in the exit dialogue 
and rebooted after each adjustment. The login was fast after them! So, there does not seem to be a general problem with saving Plasma settings.

Then I tried to chase the bug:

5. In system setting I set my external monitor as primary display and disabled the internal notebook monitor.
6. reboot
7. Login as test2 and there is the 30s-delay!
8. Change the display back to internal notebook
9. reboot
7. Login as test2 and there is still the 30s-delay!

Thus, the delay seems not to be caused by network-manager but of the
display stuff. But I could not find anything in ~./xsession-erros or
/var/log/X.org.log.

Do you know how to debug it?
