[arch-general] Which security setting in Arch prevents forwarding X apps when su root?

[David C. Rankin]

Listmates,

Which setting in Arch prevents forwarding apps when you ssh -X in an Arch box, 
su and then try to start a kde app, etc.? X forwarding works just fine as a 
user, but when trying it su'ed to root, I get the following error:

[23:29 archangel:/etc] # kwrite
X11 connection rejected because of wrong authentication.
kwrite: cannot connect to X server localhost:10.0

kdm config? X config? Any pointers/links would be appreciated.
