News: users logged out; x11vnc

users were logged out, P10: login daemon restarted, maybe reached some session limit, caused gnome shell to restart as well. Reason: many ssh sessions.
Action: reduce ssh connect collecting monitoring information.
x11vnc, take over desktop: Hannes did some work, waits for user feedback.
Debian-10 upgrade, start with P06 beginning next year
User limits, user calibration (P06, P08): status ongoing
