The extension files remain installed. The personal and VM roles do not receive them. +## External Displays + +The corporate-only `external-display@dotfiles` extension selects Mutter's +External Only layout when an external display is connected and the laptop +panel is active. Mutter selects display modes and restores the laptop panel +when the external displays are disconnected. Lid and power policies are +unchanged. While enabled, the extension overrides a manual layout that uses +both the laptop panel and an external display. + +To deploy it, run `just apply` outside the sandbox, log out and log in, then +run `just canonical-desktop`. Enabling it can immediately change the active +displays. Check connection, disconnection, and reconnection with the lid open. +Also check resolution and scaling on the external display. + +To stop automatic selection, run: + +```sh +gnome-extensions disable external-display@dotfiles +``` + +Then choose a layout in GNOME Settings > Displays.
