chroot /mnt /bin/bash --login  (for proper $PATH)

arch-chroot --- does auto mount/bind those but doesn provide the login paramer and $PATH will be wrong so dont use it.

* Video system

You can install here a desktop/login manager - gdm3, lightdm etc OR just use xinit without an GUI interface

apt install xfce4   --- it will install xorg as a requirement

Note on devual bare xinit doesnt work, it requires to many manual changes just install lightdm.
