If you don't like autologin in Armbian Ubuntu desktop, or if yo want to have several desktops to choose, here is how I did this. Tested on legacy image, but I belive that same setup should work on mainline too.   1. Install ubuntu desktop image on MMC (I did it using Etcher) 2. Install display manager. Because of simplicity, I choose LXDM.    sudo apt-get install lxdm     3. Set default session and disable nodm    Edit /etc/lxdm/lxdm.conf    Find line:      sessio
