I am connecting to a Linux server using Xming and putty on a Windows PC (necessary since Oracle does not provide collaborative support directly with Linux). If I login as a user and try XWindow features such as xclock it works fine. If I "su -" as a another user and then try XWindow I get "Xlib: PuTTY X11 Proxy: wrong authentication protocol attempted". Can anyone tell me what is going on here?
"xhost +" has been run.
