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.

You don't need to use su. Instead, use tools like kdesu or gksu to use X apps as root: $ kdesu kwrite
