OK, I've tested randr-1.2 tool. Basically, can I set output to non-connected
device? E.g., can I turn on clone without attached external LCD projector and
just plug it and have the screen?

And some observations. I have laptop with 1280x800 LFP. I've plugged external
LCD via D-SUB cable (i.e., VGA) that is cappable of 1280x1024 and some other
legacy modes.

Why VGA does not contain 1280x1024 mode?

This command
xrandr --output VGA --mode 1024x768
sets clone on external LCD, good. 

This next command
xrandr
causes legacy randr aware applications to think LFP is only 1024x768 :(
