How do I have a projector machine always mirror at 1024x768? By default new users get 1920x1200 and non-mirrored.

Here are two command line tools that will set mirroring and display resolution as you need.

Mirror

usage: mirror [option]  Passing more than one option produces undefined behavior.
  -h            Print this usage and exit.
  -t            Toggle mirroring (default behavior)
  -on           Turn Mirroring On
  -off          Turn Mirroring Off
  -q            Query the Mirroring state and print "on" or "off" to stdout

SetGetRes

Usage: ./getsetres [-l | 1..9 ] [ hor_res vert_res]

      -l  list resolution, depth and refresh rate of all displays
    1..9  display # (default: main display)
 hor_res  horizontal resolution
vert_res  vertical resolution
