What you probably want here instead is:



xhost +local:



then the X app is not limited to using only IP but can choose whichever

transport it deems best. Of course the usual safety caveats apply. If

others are on your host, they'll have X access. If you're concerned

about that, then just give root permission:



xhost SI:localuser:root



Thanks -- that was what I was trying to remember, so I just emerged it.

Looks like something I should be able to do in my .bashrc and just forget about.

Actually, it doesn't work.

What's worse, the xhost man page refers me to Xauthority(7) which does not exist, and I did
not find it with a quick check by eix.

What did work was
* xhost +root@localhost
