    I have three monitors attached to a MacPro running Lion

    When I restart, the arrangement and resolution of the monitors change in display preferences, and the primary monitor changes as well -- kind of a pain.

    All changes to display prefs are lost again on the next restart.

    Everything worked fine in 10.6.

    I tried deleting com.apple.windowserver.plist with no success.

    I searched the posts but nearly everything on multiple monitor setups refers to full screen mode.

    Any suggestions appreciated.
