Logging on via ssh does not start a full session
Somewhat off topic: is there a way to start a full session remotely?

Yes, several ways ...

Firstly, at the login window, under the menu you should see an option for remote login (at least on my Fedora7 box here, installed from the KDE live CD thats the case. On the standard Fedora7 install, or a different distro it might be label different or missing).

If you do have this you can type in the IP address of the remote session and attempt to login. Note this will only work in the sysadmin at the remote site have configured things to allow this sort of a connection (xdm I think, not sure). In any case I wouldn't want to use it over anything other than a fast (100Mb plus) local network.

Other ways include starting a VNC session on the remote service, and connecting to that via vncviewer. Another would be to use the freenx system. Googling for either of these should bring up loadds of info.

A real low level way would be to start a empty X server on your local machine, then login into the remote site via SSH, through the console for instance, export the display back to the new empty Xserver and run 'startkde' or whatever to fireup your remote session on your local X server. Again, only try this on a fast network.

On a local LAN, if you have gdm configured to accept remote sessions, you can bring up another system in runlevel 3 so X doesn't start automatically, then start it with "X -query remote_host" and you'll get a GUI login prompt followed by the remote desktop. This also works with the Cygwin Windows version with "Xwin -query remote_host". If you want to run a remote desktop in an already running X session, use "Xnest -query remote_host". However, for remote access over lower bandwidth connections and often even locally there are advantages to using freenx on the server and the cross-platform NX clients from http://www.nomachine.com. Among other things it will let you disconnect a running session and reconnect later, perhaps from a different location, with everything still running.
