This is due to the video resolution gui in gnome (or kde).  If you've
used the gui to set a mdoe it saves that configuration and resets it
when you log in.  however, it's not randr 1.2 aware so it doesn't work
well with multi-head.  It should work if you remove the keys in:
/desktop/gnome/screen/$hostname/$screennum/
