Hello,

I am just wondering wether there is a simple terminal server solution for gentoo. So basically just XDMCP with session support.

I would like to start a remote X application or desktop, lets say blender, or just openoffice, do a bit of work and let the machine then calculate whatever it wants to calculate.

Meanwhile I disconnect from the host and shut down my client. Next day I reconnect from the same machine, or, even better, from any other machine, and find the desktop as I left it – pretty much as if I just would have turned off the monitor. However, as the host does not going to run X itself, just XDM without local display, VNC is not a solution.

I tried x2go once, although only verion 2 and under debian, but it did not really work out. And I heard, nx is even worse. And and not free either.
Especially it seems that x2go is very gnome- or kde centric.

I am just running an old fashioned window manager and some non desktop integrated applications and therefore wonder wether there is a more generic solution? I do not need printing or ldap or support for USB/cdrom or any other fancy stuff, just disconnect my remote session without closing it.

That is a common desire easily accommodated by VNC or NX. I routinely use both--VNC on my LAN, NX from remote locations--for exactly this purpose. To my knowledge it is not possible with XDMCP, which is designed for a different purpose.

A VNC server uses a memory-backed framebuffer, it does not require a local display. It will happily run in the background while you are not connected.

That is incorrect. In fact, NX is by far the best option for remote X sessions over low-bandwidth links (i.e., the Internet), for which it is specifically designed. The session-management behavior is exactly as you describe.

If you search the forums you will find HOWTO guides for setting up an NX server and client or a VNC terminal server.

Thanks. Tightvnc seems to do the trick. I only knew VNC as a way to redirect the display, not as a terminal server.
