Login screen not keyboard accessible after using NoMachine

[Nick]

As far as I can tell this is related to having used the system via the NoMachine remote desktop server.

- Be at the login screen
- Connect remotely to system from another computer and start a new Virtual desktop
- Sign out of virtual desktop
- Return to system and try to log in using only the keyboard
- The current user is not selected and no combination of keyboard keys (tab etc.) are able to focus it. Only the mouse can select the user to show the password field.

I'm using a NoMachine Workstation subscription but I think the free package would be similarly affected.

I experience this in 20.04 as well: remote session with Workstation, after termination the greeter on this host does not respond to the mouse. The keyboard allows access to virtual terminals and ctrl-alt-delete reboots.

Hopefully nomachine has an answer.
