The physical desktop of a previous owner remains after switching user on the device.

As a result, the physical desktop is shown in the NoMachine session list as active. Trying to connect to this desktop causes connection with empty gray window with an active cursor and connection details.

Steps to reproduce:

1. log in on the device as another user (e.g. testuser)

2. connect with NoMachine to the testuser's physical desktop as the same user (testuser)

3. close the connection to the physical desktop

3. change desktop's owner on device to NoMachine

4. connect to testuser's physical desktop as testuser

This problem has been reproduced on systems with Wayland enabled (Fedora and Ubuntu)-
