Overview
Both SD WebUI and Jupyter are pre-wired in your GUI Desktop. Launch them from the desktop/menu, wait for the terminal to finish bootstrapping, and the Web UI opens in your browser.
- Jupyter: menu-driven launcher opens a terminal; the Web UI appears once the server is ready.
- Stable Diffusion WebUI: desktop shortcut starts a terminal to install dependencies (first run), then auto-opens the Web UI.
Jupyter — one-click launch
1
Click the top-left Applications menu → Education → choose JupyterLab or Jupyter Notebook.
Start from Applications → Education.
2
A terminal window opens. Wait until it prints the access URL; your browser tab will appear automatically (or click the URL).
Launcher terminal. Don’t close it while Jupyter is running.
3
Use Jupyter in the browser tab. Keep the terminal open; closing the terminal will stop Jupyter.
JupyterLab in your browser.
Classic Notebook in your browser.
Don’t close the terminal: it will terminate Jupyter.
Stable Diffusion WebUI — desktop shortcut
1
On the desktop, open the Start folder and double-click Stable_Diffusion.desktop.
Desktop shortcut: Stable_Diffusion.desktop.
2
A terminal will open and install dependencies on first run (usually under 10 minutes). It will then open the SD Web UI in your browser automatically.
First run installs dependencies; please wait.
Web UI opens automatically when ready.
Ignore this tab.
Heads-up: During install you may briefly see a “page not found” tab—ignore it; the UI will refresh when the server is ready.
Don’t close the terminal: the SD server runs inside that terminal. Closing it will stop the Web UI.
Bring your models
You can place models and assets via the in-container browser (e.g., download to Downloads) or CloudDrive, then move them into the app’s expected folders. Typical paths (may vary slightly by build):
- SD WebUI models:
stable-diffusion-webui/models/Stable-diffusion/ - VAE:
stable-diffusion-webui/models/VAE/ - Loras:
stable-diffusion-webui/models/Lora/
1) In your user home (Ubuntu), click Stable_Diffusion/.
2) Click models/.
3) Click Stable-diffusion/.
4) Drag files here, or Ctrl+X then Ctrl+V to move your models.
Tip: After placing models, refresh the SD Web UI’s model list if it doesn’t appear immediately.
FAQ
I closed the terminal and the page stopped working.
Re-run the launcher (Jupyter or SD shortcut). Keep the terminal window open while you’re using the Web UI.
The SD page briefly shows “can’t reach this page”.
Normal during first-time install. Wait until the terminal finishes; the Web UI auto-refreshes when the server starts.
Can I use Caps Lock in NoVNC?
Use Shift for uppercase. Caps Lock can behave inconsistently in NoVNC; keep it off to avoid inverted casing.
Mouse only, no keyboard :)
