Comment 2 for bug 351213

I just figured out that gnome-display-properties uses ~/.config/monitors.xml and I noticed that there are two configuration entries in there, with different values for my two monitors even though they're the same monitors. I don't know where this info is coming from though:

<monitors version="1">

</monitors>
