I think you did `su', not `su -'. A mere `su' merely changes your identity, but the environment stays the same. In particular $HOME. So when you launce an X-appl, the authorisation cookie is read from /home/other-user/.Xauthority, and you really being root and allowed to read anything this works. A `su -' on the other hand behaves like you logon, so $HOME now points to root's home dir and X tries to read /root/.Xauthority. Unless you've merged in the .Xauthority from the user you su-ed from this will fail. Simply running `xauth merge /home/other-user/.Xauthority' fixes this for as long as the X-cookie of that other user doesn't chance. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
