Root as a key and each user does. so when you login as user and then switch to root, it tried to use your root key to access the user session-- no go. one solution is: user% xhost + user% su root! xcalc but this is an insecure hack since in says anyone can snoop on your xserver. but if you are not on the net or have a firewall it may be used, the better solution is to 'merge' your X authenticaion key database but I forgot the command. -Kev -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
