The nomarchy-live ISO imported ./core and hosts/nomarchy-live.nix but not core/system/vm-guest.nix, which is the only place spice-vdagentd/qemuGuest were enabled. Without those agents a VM's virtio-gpu only advertises its 1024x768 fallback mode, so Hyprland's `monitor = , highres, auto` rule picks that as the highest mode and the live session boots tiny.

Welcome to the Nomarchy live environment.
|

To install Nomarchy: sudo /etc/install.sh
|

To preview the install: sudo /etc/install.sh --dry-run

To resume an interrupted run: sudo /etc/install.sh --resume
|
|
|

The graphical session autologins as 'nixos' (no password).

The 'nixos' and 'root' accounts have empty passwords.
