If your system uses the ~/.Xauthority file to hold the X access codes, then root can access the X session by simply setting XAUTHORITY to point to the .Xauthority file of the user running X. This works because root can access any file, no matter what the permissions. For example, if user bob is running X and root wants access, this'll do it (for the bash shell, the syntax is different for others) # export XAUTHORITY=~bob/.Xauthority DISPLAY=:0 -- finger for GPG public key.
