I haven't seen anybody mention this, and it was missing from http://wiki.maemo.org/Remote_desktop so I've added it there.

May be of use, I think it's pretty cool.

SSH X11 forwarding allows you to run applications on a remote computer running an X11 server and have them displayed on a local X11 client, using the SSH protocol to keep the connection secure. For the purposes of Maemo devices, this allows you to connect to your Linux machine from your N900, run any X11 application on your Linux machine, and have it forward the display and keyboard/mouse capture to your N900.

You will need to have installed an ssh client on your N900 to do this.

The below assumes you are connecting to a Linux PC called 'host', with a user account 'user'.

Open an xterminal on your N900 and type:

~$ ssh -X user@host

Answer the password prompt:

user@host's password:

You now have a CLI prompt from which you can launch any X11 applications on your Linux machine and have them displayed on your N900.

user@host:~$
