Foreword:
Just in case anyone is wondering why running an X session from your XBOX to another PC would be useful, let me give you a few suggestions.
* XBOX has no keyboard/mouse (I've not gotten around to building my USB adaptor yet, so this is why I use this method)
* Remote administration
* Remote access for friends/family
etc.

What you will need:
* Any Linux distribution on your XBOX (tested with Ed's Debian Live CD 0.0.9/0.0.10)
* X-Windows installed on your XBOX (and preferably KDE3)
* Any X11 Server (I rate and recommend X-Win32 5.4 by StarNet)
* Any SSH client (I'd stronyly suggest you use PuTTY as it's the best out there, and it's open source)

Step 1: Connecting to the XBOX via SSH
Fire up your SSH client (PuTTY if you follow good advice and connect to your XBOX, which by default has the IP address of 192.168.0.2. Remember to check the SSH checkbox, you should see the contents of the 'Port' textbox change to '22'. Enter your login as root, and then your password. If the password is still 'xbox', then change it now! You do NOT want your XBOX going online with the default password. To change the password, type this:

xbox:~# passwd

It'll prompt you to enter your new password, and again for confirmation. Notice it doesn't ask you for the original password, because you're the root user. Nice to be trusted, isn't it?

Step 2: Enabling X11 forwarding through SSH on XBOX
By default, X11 fowarding through SSH is disabled. Let's change that now. To open the SSH server config file, type this:

xbox:~# nano /etc/ssh/sshd_config

Scroll right down, and near the bottom you'll see an line called 'X11 Forwarding no'. Change the 'no' to 'yes' and you can exit, remembering to press 'y' when it prompts you to save the changes.

You can close your SSH client now, as we're moving onto the Windows side of things; we're going to install your X11 server.

Step 3: Installing and configuring your Win32 X11 server
Hopefully you've taken my advice and gone for X-Win32 5.4, in which case I can guide you though the settings. To be honest, there's not really much that you need to change here... but what you DO change has a large effect on how you want your X session to behave.

Go to Start -> Programs -> X-Win32 5.4 -> X-Config

Now, the only settings you need to decide on are on the 'Window' tab. You can forget anything about sessions, as they're not needed for this sort of implementation. If you look under where it says 'Window Mode' you will see 3 options. These options effect greatly how your windows will be viewed on your PC. Let me take you though them:
* Single - This will display one "container" window that all applications that come through the tunnel will be stored in. This is my personal favorite, as I don't tend to run just the one application at a time. With this mode, I like to run the whole KDE desktop from within it. More on how to actually execute programs later. By default, this mode is set to 'Full Screen'. I run my Win32 desktop at 1280x1024, so to keep things comfortable I run my X-Win32 window at 1152x864. Have a play around with the settings, see which you prefer.
* Multiple - This mode will run each program that comes through the tunnel in its OWN window. For example if you ran XMMS, Mozilla and Konquerer, you would have entries on your Windows 98/2000/XP taskbar for all three. Because of the sheer amount of programs I usually have open at once, I find this method to be messy. For people that will only run a couple of programs at a time over the tunnel, it might be more conveniant to use this mode.
* Both - Very messy. Try it and see if you like it, but I'm pretty sure most people will fall into either the 'Single' or 'Multiple' boats.

Once you've picked the option that sounds most appealing to you, click 'OK' to save the settings. Now open the main X-Win32 program and leave it running. We're nearly ready to create the tunnel.

Step 4: Enabling X11 forwarding through SSH on PC
Fire up your SSH client again, and as before enter the XBOX's IP and so on. If you're using PuTTY, look the white list on the left and look for 'Tunnels' under 'SSH', and click it. You should see the 'Enable X11 Forwarding' tickbox, so make sure it's ticked. Leave 'X display location' at it's default, which should be 'localhost:0'.

Now might be a good time to save the session in PuTTY now, so you don't have to keep typing the IP and enabling X11 forwarding. Pick a name like XBOX (as if I needed to tell you).

Log in!

Step 5: Creating the tunnel and using X11 on your PC
Right, so X-Win32 is open? You're logged into your XBOX via SSH? Good. Now we can create our first tunnel.

If you selected 'Single' when we configured X-Win32, and you have KDE installed, try this:

xbox:~# kde3 &

KDE should now load in your X-Win32 window.

If you selected 'Multiple' in X-Win32, try this:

xbox:~# xclock &

And then this:

xbox:~# xeyes &

I think we're done now. Have fun!
