Issue descriptionVersion: Stable / ALL OS: Chrome OS What steps will reproduce the problem? (1) Connect multiple displays to a Chrome device (2) Enable unified desktop (3) Attempt to get the display layout via the chrome.system.display.getLayout API (4) Notice that no layout is returned (5) Use chrome.system.display.getInfo to get a display ID (6) Try using chrome.system.display.setDisplayProperties to change properties using the display ID in step 5 (7) Despite using the returned ID from getInfo, setDisplayProperties says it is an invalid display ID. What is the expected output? What do you see instead? We expect to be able to control monitor layout as needed. We are unable to control the layout in unified desktop mode using the current API. The display ID error is odd, considering the ID came from the getInfo command.

Display layout cannot be controlled in unified desktop. This is a fundamental limit of unified desktop mode at the moment.

+oshima and +tbuckley, which functionality of this API: https://developer.chrome.com/apps/system_display do we want to expose to kiosk apps and WebUI in unified desktop mode? For example, do we want to enable modifying the rotation, the bounds, ... etc?

I would like this to work in kiosk mode too. Unless I'm mistaken, I can't find any way to make a window span multiple display in kiosk mode without unified desktop. But in unified desktop, DisplayLayouts and rotation are disabled, so there is only a single layout option (right with rotation 0). It's very limiting. Thanks.

@afakhry I'm not familiar with the constraints of unified desktop mode. Want to chat about this in-person at some point?
