Mark W. Eichin: . xhost +localhost maybe. xhost + is *evil* :-) . . If you're using xdm, you may find that . su --perserve-environment . . has the right effect, as it causes root to still be able to find . $XAUTHORITY, the variable that points to the file where the keys . for what ever xauth mechanism is in use is using.
Another option, useful if you su a lot from your primary id, is to put a softlink in root's home directory that points at your .Xauthority file: # cd # ln -s /home/<yourid>/.Xauthority . I forget if the softlink stays intact if you sign in as root under xdm. -- Raul
