How can I make "xhost +" the default at every boot?

I run some X11-apps as a different user than the user with which i log on to the desktop (XFCE) so after a reboot I always have to type "xhost +" in a terminal before being able to launch these X11-apps as a different user.

So how can I make "xhost +" the default at every boot?

In which config file do I have to set this to avoid having to type it manually each time?

BTW, I already tried creating /etc/X0.hosts with relevant entries (see below) as indicated in the xhost manpage but that doesn't seem to have any effect.

$ more /etc/X0.hosts
+SI:localuser:username1
+SI:localuser:username2

Another approach would be to only use 'xhost +' when you want to be the other user and then 'xhost -' when you're done. Put the following script in your path, make it executable and use it like this. I'm calling it 'swu'. You can call it whatever you like.

Open a terminal.

swu <otheruser>
(run some commands as the other user)
exit

Here's the magic sauce:

#!/usr/bin/env bash
# swu

otheruser="$1"

xhost +
su "$otheruser" 
xhost -

exit 0

Thanks, that could be a feasible workaround but surely there must be a X11 config file that gets read each time X11 is started (i.e. when logging in) in which I could put the xhost command?
