Remote login with graphical display manager (GDM, LightDM)

Is it possible to remotely (via ssh) make a login to GDM?
I'll explain a situation in which I'd need this:
I'm on my laptop and connect to my desktop via ssh. I realize there are some updates available. I install them all, but I need to reboot the computer. The problem is that once the desktop has rebooted, there will be no GDM session available, since it's necessary to log in. Can I somehow perform the GDM login remotely from my laptop?
Edit: I can't find FreeNX for Maverick, and I haven't been able to configure x11vnc + vncviewer to work. Isn't there an easy way?
ssh gdm lightdm login-screen

Install x11vnc on the remote
We assume a working ssh setup has already been done.
user@remote: sudo apt-get install x11vnc
Remote login with GDM
We assume that a successful vnc setup has already been done.
user@remote:~$ sudo x11vnc <options>
x11vnc will use our predefinded VNC settings and passwords. For further options see the manpage and this nice and elaborate tutorial.
Remote login with Light DM
To access the Light DM login screen we need to submit the Xauhority file for Light DM
ssh user@remote
user@remote: sudo su
root@remote: x11vnc -auth /var/lib/lightdm/.Xauthority -display :0
View the remote screen
On the client side launch the vncviewer (e.g. from xtightvncviewer ) as follows:
vncviewer -via user@remote localhost:0
By localhost:0 we display screen 0 on the localhost. The option -via is for using ssh.
After typing in the password for the remote login we can proceed with the graphical login.

Exactly what should I do in the remote machine, and what in the local machine... Additionaly... would that run over shh (encrypted and such)?

I'll have to install and configure vnc first... So it'll take some time to test both x11vnc and FreeNX (lil time to test... kids, also :) )

When I issue x11vnc command on the remote machine, I get a dramatic warning about not having set a password and about everyone being able to see my desktop.... How do I set a password? Do I really have to set up one?

Oh, and actually sudo x11vnc fails to start... says it can't find display

What do you mean? I installed x11vnc on the remote machine, and xnc4viewer on the local one. I have an additional problem with the vncviewer command: I'm not using public keys, but password instead, and my ssh server does not run on port 22 (default).

I just can't find FreeNX... It's not in the default repositories, and their ppa returns a couple of 404-type errors (i'm using maverick, btw)
