JFTR, graphical applications shouldn't be started via sudo but gksudo instead -> bug 1373495

Since root has access to ~/.Xauthority, I didn't try the "xauth extract - $DISPLAY | ssh ... " method, and copying ~/.Xauthority to /root/.Xauthority didn't help, anyway. X is sstarted with -auth /var/lib/gdm/:0.Xauth by gdm. There is no kerberos line in ~/.Xauthority. None of the usual fixes seem to work. Except for "xhost +" which is a really bad idea. xhost +local:root does work. Not that the man page will tell you this. This may be an X problem, not a sudo problem, but to the average user it will appear to be a sudo problem since ubuntu encourages people to use sudo rather than run as root. And other distributions do whatever setup is required to make this work.
