Description
This use case describes the scenario of logging in with multiple displays
How to test
- Log out
- On the login screen, change the display configuration
- If an external monitor was plugged in, unplug it
- If no external monitor was plugged in, plug one in now
- Log in
Expected Results
- The login screen should handle the display configuration change reasonably, e.g.
- Ignore the external display
- Clone the monitors if they have the same dimensions
- Treat the monitors as one big screen with the login screen appearing on one of the monitors
- Move the greeter to the remaining screen if the monitors it was on gets unplugged
- Not reasonable would include:
- Clone the monitors when they have different dimensions, causing the image on one of them to be either cut off or surrounded by big black borders
- Stretch the login screen over both monitors, causing the greeter to appear halfway on both monitors
- Show no greeter anymore when the monitor it was on is unplugged
