On Feisty 7.04, in GNOME logged in as my user:

peter at prospero:~ $ sudo -i
root at prospero:~# xhost
access control enabled, only authorized clients can connect
 
This is the same whether "sudo su" or "sudo -i" is used to get a root
shell. No hosts have been added to the access list.

Derek indicated that he found he could not start "kate" from a root prompt
- I wonder if this depends on KDE/GNOME ? Or alternatively, whether he was
using a "true" root shell from "su" , having set a root password?

I'm pretty sure that on Dapper any attempt to start a GUI app from a root
shell, while in a user's session, was refused... and that would be my
expectation, so I find this puzzling.
