The modes which xorg null's out are the ones your hardware cannot support. 
Only now did I notice that your laptop's native resolution is 1366x768. That 
is 768 pixels vertical. You physically cannot have 1024 pixels. Yet you write 
that you managed to force it once. Are you sure that was it?

Anyway, I don't think you can use such a mode on your laptop. Your projector 
should work fine of course, but without clone mode.

Another possibility would be having 1280x1024 workspace, which should display 
properly on the projector, but using a lower resolution on the laptop, which 
should behave like zooming because the workspace is bigger. I don't know how 
to do this off the top of my head, but it should be in the man pages.
