It has to do with Xauthority files. I don't understand all the
ins-and-outs of it; I just use "sudo" instead (as in "sudo eog"), which
handles it automagically.

I think "sux" (and perhaps another tool or two) might work as well.

Or you can dig into the ins-and-outs, and figure out how to copy the
Xauthority info from your normal user to root when you "su".
