If you're suing to root, just do:
        export XAUTHORITY=<home of the user you were>/.Xauthority

If you're suing to someone else:
As the user you're suing from:
        xauth list
As the user you're suing to:
        xauth add <paste here the <yourmachine>/unix:0 line>

Recommended lectures:
        (3x)Xsecurity
        (1x)xauth
        (1x)xhost
