Monitor placement not saved across reboots

[Justin Stressman]

I have 3 monitors setup for my desktop and arranged via the Display settings.

Each time I reboot however, their placements revert and my middle and left monitors end up swapped again.

Trusty Tahr 14.04 64bit nightly build, updated today (April 13th)

Will gladly provide more info if needed (I'm having trouble finding information on how to add proper information to these bug reports, since the process is apparently not the same as stock Ubuntu?)
