Comment 10 for bug 1287341

I've gone through all the relevant upstream commits, and here are my conclusions:

1) The upstream code covers the use case of Wacom tablets with built-in displays (which, although useful, is not the use case discussed in this bug report). It would be way too much code to backport, especially for an SRU.

2) The upstream code covers the use case mentioned in the original description of this bug report, but I think backporting the new GsdDeviceMapper (a tool to couple input devices with displays) to unity-settings-daemon would be an overkill, just for this single use case. This said, introducing the GsdDeviceMapper is something definitely worth exploring, as a long term plan.

3) I can provide a fix for the use case in the original description with a much smaller amount of code. For this reason I'm going to complete and integrate my current prototype with the unity-settings-daemon. The result will be effective and good for an SRU.
