Description Dan Dascalescu 2016-09-03 19:57:19 UTC 
I have a Dell E7450 laptop, connected via HDMI to a NEC monitor. This monitor is detected correctly in Display Configuration, and I made it the primary monitor, and moved the task bar to the bottom of that screen.

Reproducible: Always

Steps to Reproduce:
1. Disconnect NEC monitor
2. Connect instead Philips TV via the same HDMI cable
3. Open Display Configuration

Actual Results:  
The NEC monitor still shows up as the connected monitor.


After disconnecting the TV, and using only the laptop, the task bar is completely gone (I mean the horizontal strip including the K logo, the task bar and the system tray panels).

Windows that were maximized on the TV screen are no off-screen.

In this situation, Mint Cinnamon, Unity, and Windows 7 would bring the task bar onto the only display available. Some of these OSes would also reposition windows so they're at least partially visible.
