Display configuration tool (using nvidia drivers): I use disper for output configuration and xrandr for rotation.
For those not in the know, disper is incredibly useful if you use the nvidia driver and frequently configure displays (one line to switch to laptop panel/external display/clone mode/extended desktop mode).
Michael, you missed "single display, configured with other tool". I frequently use an external display attached to my laptop rotated to portrait orientation (since nvidia drivers have very very limited support for per-screen rotation settings).
