Detach/reattach an application run on X over SSH?

Question

I have a development server that I leave running all the time, and a development laptop that I turn off/on everyday.

I have a GUI application on the server that I'd like to run over SSH -X, and I'd like to leave it running even when my dev laptop is powered off.

Is there a way to detach and then re-attach to that application over SSH -X?

I'd prefer not to use VNC in my case.

Answer 1

Xmove should be able to do what you want.

Here is a howto (dated 2006).

Answer 2

There's xpra, a slightly more recent tool than xmove.
