Linux filter: Is there an equivalent to GNU screen for X Windows?

I want to be able to leave a program running on a server at home, "attach" to it from a remote computer with X (probably Xming) to use that program, then "detach" while leaving it running.

I can do this with linux console applications using GNU screen, but Google has not turned up a way to do this with X applications. It's possible that this is because I don't know the correct terminology to search for -- "screen" is not a useful keyword when searching with other GUI words.

VNC would work, but would not be ideal -- I like using an X server so the remote applications can coexist easily with my local applications.

This isn't quite what you're looking for, I don't believe, but it may get you started in the right direction.

If it's X-to-X, you can do something like "export DISPLAY=hostname" an have windows from a remote X session started on yours. I'm not sure if you can attach to an existing one, though. I also don't recall the exact syntax, as it's been years since I've done it.

A link with more information on what I just mentioned.

Yipe. You could do that, but it's all in the clear and a bad, bad idea. Luckily, SSH does X forwarding.

This should work:

ssh -X hostname
*start X app*
bg (close the ssh session and the app will die, so leave it open)
detach screen when done

You make want to look into xmove.

Combine this with ratpoison as your WM if you are a total screen purist!

I believe NX, in either its free or commercial implementations, can do this. I think it'll even do application-level as well as framebuffer-level attach/detach. I haven't used it myself, although I've been meaning to check it out.

NX is what you want.

Thirding NX. It's exactly what you want.

You may also want to look into XVNC. To applications, it's an X display, but to remote users, it's a VNC server. It's also available with many standard Linux distributions.
