When I do 'init 5' kdm loads (and display the logon screen) but after entering my username/password it hangs at the KDE splash-screen (the last icon, so some progress must have been made). Caps lock then won't even work, but emergency sync seemed to do the trick. /var/log/warnings: Apr 15 07:55:11 linux-7vph nm-dispatcher.action: Script '/etc/NetworkManager/dispatcher.d/autofs' exited with error status 1.
