[Solved] Installer drops me on a terminal screen even with graphical installer

Help
1

First time using NixOS, trying to switch from Arch. I flash the Plasma installer image onto a usb drive and boot from it, but I get dropped to a terminal with no graphical installer in sight.

sudo systemctl start display-manager does nothing either.

I have an Nvidia GPU, but I’m extremely new to Nixos and am not certain how to install the drivers. Looks to me like /etc/nixos/configuration.conf is just for the live usb, and not to be edited either.

Fixed it by:
using the gnome installer and just selecting Plasma in that option.

Rebooting from the installer dropped me back into the tty, but now that i could log into my account, i added services.xserver.videoDrivers = [ "nvidia" ]; to /etc/nixos/configuration.nix, ran nixos-rebuild --switch, and a reboot brought me into plasma.

Sorry if this is super obvious, but I really am new to this world!
