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

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. -- David C. Rankin, J.D.,P.E.
