On a few occasions when I was stuck, I'd screw a 2x4 to the wall at the end of the lid and along the wall an inch down from the ceiling studs. Then lay one end of the rock over the butt end, step back into the sheet and slide it on to the longer piece of wood along the wall. Then tack up the loose side and work your way around. I also cheated by pre-anchoring screws into the face of the board before I lifted it.

This would only work if the room was under 20x12 so I could stagger the butt seams and only had to straight arm one row. That's only a 4 foot span between butts so you have to watch the direction of the lighting coming in through the windows. Depending on the layout of the board, some rooms worked better to run the rock parallel to the studs.

I don't recommend it, but it will work in a pinch. It's better than losing the day waiting to start the job with a lift or a helper.

Of course if you want to do it the smart way...you would consider that lift...
