   Finding why ssh -X does not work anymore is a good thing. But your
comment that says you cannot run programs as root anymore suggests that
your are using ssh as a kind of 'su' alternative.
   In that case I suggest that you look at sux, an su-wrapper script
which will do the xauth magic necessary for root to get access to your
screen. Instead of typing 'su -', just type 'sux -'.

   You can get sux there:

and the Readme:

   One advantage is that with sux your X connection does not through
the encryption/decryption cycle. But one thing it does not do is forward
you ssh-agent.

   I which there was an ssu so that I could do 'ssu -A -X - foo' and
have ssu login into my foo account (using a public key for instance),
set up the xauth stuff and forward the ssh-aget connection. But not go
through the encryption/decryption of each X packet!

   Well, I hope you will find sux useful.
