Connect the projector 2. Switch to console with Alt+Ctl+F1 (or F2...) 3. Toggle to projector setting (or shared setting) As you are in text the projector will beam the command line. 4. Start another X session by command startx -- :1 This works for me almost always subject to X resolution being within power of projector. By experience mostly 1024x768 works.
