After touching the touchpad the screensaver stops, but the screen is black. I managed to find the password text field by observing the mouse cursor, which changed above it. After typing the password, the screen was unlocked and mouse cursor changed above the elements, an application had focus (Google Chrome) -- but the screen was still black.
