The need_rotate variable is only used once anymore and had semantics which lead to errors in the past. In particular when negated we are dealing with a double negation. The variable gets replaced with a simple check on the xdg-output directly. Signed-off-by: Roman Gilg <subdiff@gmail.com>
X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
