You can set up the screen saver so that it is activated either automatically or in response to a key combination (hotkey). You can also select a password option. The look of the taskbar can be configured separately for the login dialog and the locked screen.
Example configuration of a screen lock:
The screen can be locked via taskbar or desktop icons or using hotkey Ctrl-Shift-L.
The screen lock starts automatically after 5 minutes without user action at the thin client. The screen lock can be stopped by entering a user password or administrator password (see Password).
The locked screen does not display the taskbar until the login dialog appears. The user can bring up a soft keyboard, e.g. to login using touchscreen monitor.
