After I upgraded from 18.04 to 20.04, whenever I am making a connection
to a VPN server (using Network Manager), vino-server will stop when the
VPN connection is established.
This did not happen in 18.04 before the upgrade.
syslog show the following when I connect to VPN
10:02:00 systemd: Stopped Vino VNC server.
