Please describe your issue below:

I use Real VNC server for remote connection to my Khadas Vim 3 pro. When I use Ubuntu 20.04 with the desktop environment - I can simple install Real VNC server using instructions here: [Install RealVNC Server on Ubuntu 20.04 for Remote Access - Learn With Omar](https://install instructions) and it works perfect . But if I install Ubuntu 22.04 - that recipe doesnā€™t work. I can not connect remotely to my Khadas Vim 3 pro with Ubuntu 22.04. I have also a Raspberry Pi 4B and I can not also install and use Real VNC server on the modern Raspberry Pi OS (Debian buckworm) but it worked successfully on the old Raspberry Pi OS (Debian bullseye). In Raspberry Pi 4B I have menu ā€œraspi-configā€ where I can switch off wayland (instructions how to enable Real VNC on the modern Raspberry Pi OS). Maybe I need also to switch off something on Khadas Vim 3 pro to enable ability to use Real VNC server? What was changed in Ubuntu 22.04 which broken the Real VNC-support?

Post a console log of your issue below:

For Ubuntu 22.04 version, since it uses Wayland as the display server, the traditional VNC remote desktop method may not be suitable.

And what should I do? Can I switch off Wayland? Or maybe I can do something else to connect remotely to my Khadas from an Android tablet

Before I reinstall my Ubuntu 20.04 and try this commands on Ubuntu 22.04 I want to know:

are this instructions also useable for Ubuntu 20.04? Can I try this on the actual Ubuntu 20.04 to be sure that this instructions are workable?
