@seb128: I tried two things.. First i used the NetworkManager.service from 15.10 which was a bit different, but same result.
Then I reverted back and got the full log from syslog. here: http://paste.ubuntu.com/16475211/ You can see on line 90, May 17 16:18:36, that is where i login and all is well, just before that: May 17 16:18:31 desktop NetworkManager[944]: nm_settings_connection_delete: assertion 'NM_IS_SETTINGS_CONNECTION (self)' failed May 17 16:18:31 desktop NetworkManager[944]: <info> [1463494711.7295] audit: op="connection-add-activate" pid=1282 uid=108 result="fail" reason="Insufficient privileges."
