It was pointed out to me that this is nothing special about OW but common
for (older) X11 Releases. In Fact, one of OWs biggest Pluses is that it
usually *doesn't* follow X11 Specs in this, instead it uses the xauth(1)
Mechanism. Thus, the_wise_Thing (tm) to do is something along the Lines of:
access control enabled (only the following hosts are allowed)
kleopatra:/home/TI/bern# setenv DISPLAY :0
kleopatra:/home/TI/bern# setenv XAUTHORITY ~bern/.Xauthority
which allows root (who, of course, can read ~bern/.Xauthority) to display.
Since some People didn't know why I'm not fond of "xhost +localhost",
let me point that out, too: This allows ANYBODY on the local Host to
fumble around with your X11 Server, not only to display whatever he
chooses, he can even monitor X11 Events like Mouse Movements and
Keystrokes! Rather bad if you continue to su ...
