On the host, the option to change from “Desktop not shared” to “Desktop shared” is not displayed, and I am stuck with “Desktop not shared” – I cannot change it because I do not see the other option.
On the client, I receive the following message when attempting to connect to the host:
Cannot detect any display running. Do you want NoMachine to create a new display and proceed to connect to the desktop?
Previously, NoMachine would automatically connect me to my Ubuntu desktop, allowing me to control my physical machine.
