Understanding VNC Server modesΒΆ

If you have an Enterprise subscription, you can run VNC Server in different modes, to provide remote access to computers in different circumstances, and meet different needs.

Note

If you have a Home or Professional subscription, only Service Mode is available.

Service Mode
All subscriptions

VNC Server remotes the console of the computer. Connected VNC Viewer users see exactly what a person sitting in front of the computer would see.

This is either the desktop of the currently logged in user, or else the login screen.

User Mode
Enterprise subscription only

VNC Server remotes the desktop of the currently logged in user only. Connected VNC Viewer users see exactly what a person sitting in front of the computer would see while the current user is logged in.

VNC Server automatically stops (and VNC Viewer users are disconnected, and cannot reconnect) as soon as the current user logs out. The login screen cannot be remoted.

Virtual Mode
Enterprise subscription only
Linux platforms only

VNC Server creates and remotes a virtual desktop. Connected VNC Viewer users therefore do not see what a person sitting in front of the computer would see.

Instead, they gain access to a persistent private workspace. The virtual desktop is not destroyed until VNC Server is explicitly stopped. The login screen cannot be remoted.

You can start VNC Server in Virtual mode on an ad-hoc basis or run it as a service to create virtual desktops on demand.

If you have an Enterprise subscription:

  • VNC Server can run in Service Mode and User Mode concurrently, though this is not generally useful, and likely to result in port conflicts.
  • VNC Server is designed to run in Virtual Mode as many times as you have computers in your tier (referred to as desktops). It can safely be run concurrently with either other mode.
  • VNC Server in Service Mode supports both cloud connectivity and direct connectivity. The other two modes support direct connectivity only.
