I type Win+L to lock the session 2. Laptop shows locked screens, then all display outputs get suspended 3. External display detects no input signal and enters power saving mode 4. Laptop somehow detects the external display being disconnected, wakes up and resizes the desktop to single-display configuration (2560x1440) 5. External display wakes up on input signal from the laptop 6. Laptop detects the external display being connected, resizes the desktop to dual-display configuration (5120x1440) 7. Loop over 2-6 On Ubuntu GNOME 15.10 it worked as expected, after step 3 all displays kept suspended until I touched my keyboard or mouse.
