Like Erik mentioned, you need to tell GDM to listen on a tcp port.

Also, please do not use xhost. Use xauth instead. For example,

[lpc1 ~]$ xauth extract someTemporaryFilename :0.0

Then transfer the auth cookie to lpc2 via sneakernet, ftp, etc.

[lpc2 ~]$ xauth merge someTemporaryFilename
[lpc2 ~]$ xclock &
