+==== Change Keyboard Configuration on Console. Important! ====
+Before you change the boot target (aka runlevel) to multi-user.target, i.e. without GUI, you should change the keyboard configuration first in case you are not using an English keyboard layout. A wrong keyboard layout can cause a lot of trouble. It can even prevent you from logging in when your password is using characters affected by the layout configuration.
+Open a terminal window and execute '' sudo dpkg-reconfigure keyboard-configuration''.
+Test it on a tty terminal, too, because that is what you get if you change the runlevel to other than graphical.
+Press ''<crtl> + <alt> + '1' ''  to get to a tty terminal. Test your credentials. A wrong keyboard layout may compromise your password typing.
+==== Change target / runlevel ====
+<code>
+systemctl get-default
+# change target of current session
+systemctl isolate multi-user.target
+# systemctl isolate graphical.target # Use this to get back to graphical mode
+# set default target
+systemctl set-default multi-user.target
+# systemctl set-default graphical.target # Use this to get back to graphical mode
