Public bug reported: In a multi-display setup where displays have different resolutions (e.g. external display connected to laptop), the login screen forces the same resolution on both displays. For example in my setup I have a laptop with a 16:9 ratio and an external screen with a 4:3 ratio. The background appears on both displays and the login box appears on the laptop's built-in display. However, both displays are forced to a 4:3 resolution that only fits the external screen.
Steps to reproduce: 1. Connect an external display to a laptop with different ratio (e.g. 16:9 laptop and 4:3 external display) 2. Start the laptop 3. The login screen appears Expected behaviour: Each display shows an image that is scaled according to their individual resolutions Actual behaviour: Both displays are forced to a degraded resolution that can be displayed by both. E.g. in my case the laptop has a max resolution of 1366x768 while the external display has a max resolution of 1280x1024: the resolution used by the login screen is 1024x768 i.e. a 4:3 resolution (like the external display) but with 768 vertical resolution (which is the max vertical resolution of the laptop).
