Most of the DE monitor tools will remember your settings, but if not,
something like the following in your xorg.conf:

Section "Monitor"
        Identifier   "Displayport-1"
        Option       "Rotate"           "Left"
EndSection

Section "Monitor"
        Identifier   "Displayport-0"
        Option       "Rotate"           "Left"
        Option       "RightOf"          "Displayport-1"
EndSection
