Xvnc will do it but that costs you a lot of desktop performance as VNC
doesn't expose things like compositing hardware acceleration (or much
acceleration at all) across the interface.

In theory disconnect/reconnect is a toolkit problem, but toolkits that
support it are a bit lacking. A pity really because another natural use
for this is virtualisation - moving your desktop virtual machine between
your desktop and laptop and other machines when travelling or switching
