RDP on Ubuntu Desktop 22.04

Question 1

I installed Ubuntu Desktop 22.04 and want to connect through RDP or VNC. I found screen sharing and enabled RDP. I know the IP of the machine, so I gave it a try. Well, it's not working.

I then found that the Xrdp protocol needs to be installed, so I installed it. Still not working. I also read that it should work with Windows 10/11 RDP, so I tried with Windows 10 RDP from the same network, but still not working.

I can ping the Ubuntu PC, that's something.

Is there a proper explanation of what I should do to make it work?

Question 2

Installing xrdp is counter productive.

@DBoltons'answer is helpful already but missing the screenshots you see below.

In my environment i have got 4 Ubuntu 22.04 LTS systems on which i am trying to get RDP Screensharing to work. I was only successful for two of the systems so far - and both do not have xrdrp installed!

First you might want to note that you need proper authentication - a password is generated which you need to use

otherwise you might see an error message such as:

In settings/about i got:

To avoid the session to disconnect itself when the screen save kicks in you might want to change Settings/Privacy/Screen

Please also note the followup screen sharing issue:

Screen Share Not working in Ubuntu 22.04 (In all platforms zoom, teams, google meet, anydesk , etc.,)

It seems as of 2022-11 you can either have remote desktop sharing with wayland or screen sharing via zoom but not both at the same time!

Here is a list of links i checked so far - beware some of the information provided by these links might be misleading - the situation seems to be quite confusing as of 2022-11.
