I upgraded to Fedora 17 using a new install of / but keeping my old /home on a different partition.

My laptop is usually attached to a dock, and f16 handled that fine. I had the 2 displays one on top of the other and the higher resolution external display had its high resolution and the lower resolution laptop one kept its. I usually have the laptop closed and don't use it.

But now there's a "unify" checkbox in system settings and if I use that then the external display is forced to the low laptop resolution but if I don't unify then the "main" display is the laptop and various saved windows are not on the external monitor. I can't work just using the external monitor but have to have both open.

So I have to disable the laptop display which is annoying. (and what effect would saving that have if I boot up without the external monitor?)

is there a way to get back to the previous behaviour?
