If I do
xhost + >access control disabled, clients can connect from any host su AnotherUser -c xterm
an xterm pops up. However if I do
xhost +SI:localuser:AnotherUser >localuser:AnotherUser being added to access control list su AnotherUser -c xterm
No protocol specified, I'd like to understand why it doesn't work.
I am in Debian sid amd64
