Setup
I have installed Ubuntu Server 21.10 on Raspberry Pi 400, configured it as described here and to get desktop environment I have installed Ubuntu MATE by running sudo apt install ubuntu-mate-desktop.
I have installed and configured tightvncserver to remote access the machine.
I am able to ssh and vnc to the machine.
Issue
I am not able to manage wifi from the taskbar also taskbar looks incomplete.
Screenshot of the desktop.
I have tried few online suggestions like restarting NetworkManager or removing unused packages, but nothing helped.
Not sure if I need to install any missing package, appreciate any help.
PS:
I have to go via this route i.e. first configure Ubuntu Server then install desktop environment because I want to do it headless without any external monitor.
