I have a jammy Armbian install on one of the (really) new IndieDroid Nova devices. I have changed /etc/gdm3/custom.conf, setting AllowRoot=true and /etc/pam.d/gdm-password, disable root quiet setting. Typical of what you do for Debian to enable explicit user/password input of the Gnome greeter. But with Armbian jammy, I still only get the default 'ttt' user forced on me, and the only value I can enter is the password for ttt. How to get the user list to appear so I can select ANY user and enter the password?
