====  Add user to xorg auth (xhost) by username ====

In order to **allow user to interact** with the xserver of your xorg instance,
you must allow him to do so. You can do it in the **insecure way** by allowing all local hosts to access the xorg instance, or either allowing **just a certain user** to do so.
<code bash>
# allow all hosts in the local domain to access the xorg instance
xhost +local:

# allow only the specified localuser to get access to xorg display
xhost +"si:localuser:USERNAME"
