Description
This use case describes the scenario of adding an extra monitor while logged in
How to test
- Log in with a single monitor
- Plug in an extra monitor. This can be done in several ways:
- Plug an external monitor directly into the laptop
- Plug an external monitor into the docking station that the laptop is docked to
- Dock the laptop into a docking station that has an extra monitor plugged in
- Make the desktop aware the new monitor. This can be done in several ways:
- Use the 'display' hotkey (bound to Fn-F7 or a similar key combination on many laptops). Use that key to cycle through predefined monitor configurations
- Open gnome-display-properties (available in the menus under System → Preferences → Display). Use the 'Detect Monitors' button.
- When 'Show displays in panel' is checked in gnome-display-properties, clicking on the displays statusicon.
- Configure the two monitors in the way you want in gnome-display-properties. Also try some more 'exotic' configuration, like rotated displays, and verify that you can revert these changes after trying them out for a few seconds.
- Use various applications on your multi-monitor desktop. Try things like
- fullscreen apps
- playing a movie
- 3d
- Turn on desktop effects on your multi-monitor desktop
- Lock the screen
Expected Results
What is reasonable?
Note that we ask for you to judge whether the system behaviour is 'reasonable' or not, without prescribing the exact outcome. If some aspect of the system behaviour is surprising or confusing to you, it is probably worth pointing out.

- gnome-display-properties and the displays statusicon should show the same set of monitors, in the same way (i.e. same names, same colors, etc). The should show exactly the connected monitors, none should be missing, and there should be no 'ghost' displays.
- The desktop should adapt to the new monitor.
- The panels should not be stretched across monitors, and must not appear in the middle of the screen
- The desktop background should adapt to the new screen dimension - depending on the current background image, that might cause a different image to be displayed. E.g the default F11 background shows a lion in dual-monitor configurations, but not when only a single monitor is used.
- If you have used the current combination of monitors together before, the desktop should remember the last configuration and reestablish it upon login. E.g. if you had the external monitor on top of the laptop panel, that configuration should be remembered, even if you have used the laptop without the external monitor in the meantime.
- gnome-display-properties should show meaningful names for your monitors, the internal display should just be called 'Laptop' or similar, while the external monitor should be identified with a vendor name.
- Multiple consecutive display configuration changes should work.
- The 'display' hotkey should cycle through a reasonable set of display configurations.
- Fullscreen apps should behave 'reasonably' in a multi-monitor setup
- Playing movies should work as well as in a single-monitor setup, on all monitors
- 3d should work as well as in a single-monitor setup, on all monitors
- The screen locking should behave 'reasonably' in a multi-monitor setup, ie
- The screensaver should cover all monitors
- The lock dialog should appear on one monitor, not stretched over all of them
