+  VM initialization complete!
+
+  For Sway/Wayland to work:
+  1. The VM needs GPU acceleration
+  2. User 'debian' added to video, render, seat groups
+  3. seatd service enabled for Wayland sessions
+
+  Login with:
+    Username: debian
+    Password: nixos
+
+  To start Sway manually:
+    sway --unsupported-gpu
+
+  Or SSH and run: dbus-run-session sway
+
+  Important: Sway is installed but requires a workaround for the virtual environment.
+
+  To start Sway:
+  1. SSH into the VM: ssh debian@localhost -p 2222
+  2. Run the launcher script: ~/start-sway.sh
+
+  This script starts an X server and runs Sway within it using XWayland.
+  The display will be accessible via the QEMU GTK window.
