$ vncserver -localhost no -geometry 800x600 -depth 24,

It works fine in local LAN with RealVNC on an Ipad, however for some reason, the server startup via systemd does not work, the service status log shows an inactive status (dead), what would be the problem? I’ve tried doing the systemd procedure locally on a server Terminal, and remotely via SSH, also checked the proper username in the script and rebooted with no success and ran out of ideas, your kind help is required, the status log is down below.

Please let me know your ideas or suggestion to remedy this issue.

Thanks and regards

PS: during the interim, I also experienced the problem that when a desktop session was already started, locally or remotely an attempt to start a second session remotely or locally would fail with the error “could not acquire name on session bus“,

This problem was fixed, as per unix.stackexchange.com by adding the following line to ~/.vnc/xstartup:

unset DBUS_SESSION_BUS_ADDRESS

After applying this patch, I can now have concurrent desktop sessions, locally and remotely, I can also have a Mate desktop running locally on the server and a cinnamon desktop remotely on my iPad via RealVNC.
