[lxc-users] Running unprivileged gui container in Arch Linux

[Tom Weber]

You're describing a X11 Access Control problem - probably off topic for
lxc-users.

xhost + is the crudest way to open your X Server for basically anyone.
With all security related things you better understand what you are
doing - thats why I don't give you a couple of commands here ;-)

Try googling for 'X11 access control' in order to understand how that
works.
