Need to have keyboard connected the first time to allow ssh through raspbi-config. Do the full-upgrade first.

sudo apt update
sudo apt full-upgrade
sudo raspi-config

sudo apt install xserver-xorg xinit x11-xserver-utils xterm firefox-esr

Not sure if I need

sudo useradd -G tty pi

Got it working with Raspberry Pi OS - Desktop on RPi4 and installed these packages:

sudo apt install libts-bin evtest

... and sudo ts_calibrate to calibrate the touch screen.
