I want to remote login to another laptop to continue working on session left over. VNC is slow because it's bandwith hog. I know (or I think I know) that it's not latency, it's bandwith because the first update from the top of screen or the top of recently changed view occurs very fast, but the entire redraw takes time.
I believe that X doesn't send the pixelmap, but instructions on how to redraw screen. So I'd like to use X.
Question: Is there a way for me to say, to all the applications, please now migrate to the X server available remotely? Or can I make my computer think that what it calls :0.0 is no longer attached to the monitor, but is now on a remote machine. (And can I reverse this process so that I can switch back to the other laptop whenever I want)?
