# Final message
final_message: |
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
Setup completed:
1. Git cloned GRCon23Tutorial repository
2. Ran ./install.sh
3. Started Jupyter Lab on port 8888
Login with:
Username: debian
Access:
SSH: ssh debian@localhost -p 2222
Password: nixos
Jupyter Lab: http://localhost:8888 (forwarded from VM port 8888)
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.
Check status in VM:
sudo journalctl -u cloud-init
cat /var/log/vm-init.log
