After upgrade to jaunty, cannot use gksu or log in via ssh

[Kevin O'Gorman]

I have a Dell inspirion laptop on which I installed intrepid about a
year ago when I got it.
I upgraded to jaunty yesterday and while most things are working for
me, there are still two things that don't.

1) gksu does not work.  The first time I use it, it silently fails
with return value 1.  The second time it gives an error message that
it cannot contact the gconf daemon.  This suggests that the first
attempt has killed the daemon as well as causing an error.  I have no
idea what to do about this.  My usual command-line is
   gksu -u root x-terminal-emulator
this worked fine in intrepid.

2) As a work-around I tried logging in via ssh, but there appears to
be no ssh daemon despite my attempts to configure it.  The connections
on port 22 are always refused.

Any help?
