I have a few windows apps (render nodes) that require wine and the desktop to run, I have a headless box and would like to use it to help in rendering, what is the best and easiest way to use the box remotely?

I have googled this and ssh x tunneling is one option, vnc is another, i need to be able to use the box without having to have any remote windows open here as i dont want this pc on in order to use the headless box

X over SSH isn't really an option for what you're asking. The simplest thing that'll work is an xvfb server on the remote box and connect using x11vnc. It was a bit of a pain to set up last time I used it, but that was years ago.

If you can put it into a KVM/Xen virtual machine I'd recommend that instead, libvirt handles all the details automatically and gives you a VNC/Spice remote connection by default. It works at the kernel GPU driver level so everything works like a local install (including the VT consoles), but in a window.

There doesn't seem to be anything on the Gentoo Wiki about using libvirt, unfortunate...

KVM has a wiki here, libvirt has some docs, but IMO they're both not much use for learning it.

Xen has pretty good documentation but it takes a lot of reading before you get somewhere usable with it. Pays off eventually.

I'd say the best way to start off is to install virt-manager locally and just play around with its GUI and running livecd ISOs under qemu. If that looks like what you want, doing it remotely is just a matter of installing libvirt on the server and connecting to that with the GUI.

Running under a regular VNC server without Xvfb or x11vnc sounds simplest, unless these programs require special support from the graphics server.

That's something I hadn't even thought of - run VNC under wine? No need for X at all if that's possible...

No, run VNC under Linux. Then, run Wine with the display server set to VNC.

Oh, I didn't know VNC could work as an X server. That's useful to know.

I tried x2go a couple of months ago. I just worked out of the box, which is unusual for this kind of thing :)

Have to agree I like x2go, though I found it didn't quite "work out of the box", the client cannot use ecdsa ssh keys so you have to create an rsa key. Confused me for a while :oops:

Edit: There is one other minor annoyance with x2go, when resuming a suspended session I need to run setxkbmap to have a fully functional keyboard(still lose DELETE key though), that may be due to my set up and any suggestions appreciated /Edit

Have recently noticed xpra available in portage

http://xpra.org/

and the changelog suggests it is being actively worked on

http://gpo.zugaina.org/x11-wm/xpra/ChangeLog#ptabs

Not tried it myself as yet, but it sounds interesting and I intend to run a test at some stage

maybe its not exactly what you asked for, but i would try Virtualbox.
its suposed to have 3d acceleration, and has a built in remote desktop option, and you can run headless virtuals from the cli
