InputClass sections use various MatchFoo directives to decide which device to apply to. This usually works fine for specific snippets but has drawbacks for snippets that apply more generally to a multitude of devices. This patch adds a NoMatchFoo directive to negate a match, thus allowing snippets that only apply if a given condition is not set. Specifically, this allows for more flexible fallback driver matching, it is now possible to use a snippet that says "assign driver foo, but only if driver bar wasn't already assigned to it". For example: Section "InputClass" Identifier "libinput for tablets" MatchIsTablet "true" NoMatchDriver "wacom" Driver "libinput" EndSection The above only assigns libinput to tablet devices if wacom isn't already assigned to this device, making it possible to select a specific driver by installing/uninstalling it.

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.
