 # Final message
 final_message: |
   VM initialization complete!
 
-  For Sway/Wayland to work:
+  Setup completed:
-  1. The VM needs GPU acceleration
+  1. Git cloned GRCon23Tutorial repository
-  2. User 'debian' added to video, render, seat groups
+  2. Ran ./install.sh
-  3. seatd service enabled for Wayland sessions
+  3. Started Jupyter Lab on port 8888
 
-  Login with:
+  Access:
-    Username: debian
+    SSH: ssh debian@localhost -p 2222
     Password: nixos
+    Jupyter Lab: http://localhost:8888 (forwarded from VM port 8888)
 
-  To start Sway manually:
+  Check status in VM:
-    sway --unsupported-gpu
+    sudo journalctl -u cloud-init
-
+    cat /var/log/vm-init.log
-  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.
