+There is a mode for turning all displays at once called panic mode:
+
+.. code:: shell-session
+
+   user@localhost $ pyrandr.py -a
+
+And most interesting part is ability to turn on selected outputs side by side
+in horizontal layout, for example:
+
+.. code:: shell-session
+
+   user@localhost $ pyrandr.py -p VGA1 VGA2 VGA1
+
+Will switch off all other outputs, but ``VGA1`` and ``VGA2``, and place those
+outputs in order ``VGA1`` on the right of ``VGA2``. The option ``-p`` will set
+``VGA1`` as the primary output.
