Xnest for remote Gnome session

One fairly nice way to get a remote gnome session with a minimum of fuss is to use Xnest. This just makes a little X server in a window.

Firstly, setup xauth to allow you through

ianw@lime:~$ echo $DISPLAY
ianw@lime:~$ xauth list
localhost.localdomain:0  MIT-MAGIC-COOKIE-1  bd72c2....6c8ab8
lime/unix:0  MIT-MAGIC-COOKIE-1  9a5c6...648d4bffd
localhost.localdomain/unix:0  MIT-MAGIC-COOKIE-1  9a5c6b555f...bffd

Copy the cookie that corresponds to your current display to a new one for display :1

ianw@lime:~$ xauth add :1 MIT-MAGIC-COOKIE-1  bd72c2....6c8ab8

Then startup Xnest on display :1

ianw@lime:~$ Xnest -auth .Xauthority :1 &

Then fire up an xterm that ssh's to the remote box and starts up something like gnome-session

ianw@lime:~$ xterm -display :1 -e ssh tutti gnome-session

and hopefully it will look something like this!
