SYNOPSIS
========

xdeadzone <[**-i** **-b** | **-w** ]> <**-n*> [**-nw** | **-ne** | **-sw** | **-se** | **-abs**] *geometry*

xdeadzone **--help** | **--version**

DESCRIPTION
===========

**xdeadzone**'s job is to create a window of a specified size and
position, and prevent the mouse pointer from entering it.

The intended use for it is to keep the mouse out of the "dead zone"
of a multi-head X display where the monitors don't all have the same
resolution.

It could also be useful for covering annoying parts of the screen,
e.g. advertisements in ad-driven software like the Opera browser, or
Adobe Reader. Use **-abs** (absolute positioning) mode for this,
and either **-b** or **-w** to make the window visible.

By default, **xdeadzone** doesn't display a visible window. It stays
on top of other windows, and is present on every virtual desktop.
If run with **-b** or **-w**, it'll appear as a solid black or white
rectangle with no title bar or window frame... although if you're
using it to block the mouse from a dead zone, you won't be able to see
it anyway. If you want a titlebar (and a movable window), run with **-n**.

**xdeadzone** has been tested with various window managers and desktop
environments, and works properly with at least: KDE (Plasma 5), XFCE
4, Fmwv2, WindowMaker, BlackBox, and FluxBox.

OPTIONS
=======

Options can appear in any order on the command line.

Modes
-----

One (and only one) mode option is required.

**-nw**
  Place window at northwest (top left) corner of display.

**-ne**
  Place window at northeast (top right) corner of display.

**-sw**
  Place window at southwest (bottom left) corner of display.

**-se**
  Place window at southeast (bottom right) corner of display.

**-abs**
  Place window at the coordinates given by **geometry**.

Required argument
-----------------

**geometry**
  This is a standard X11 geometry specification. Its format is
  <*width*>x<*height*> for all modes other than **-abs**. For **-abs**,
  it's <*width*>x<*height*>[*+-*]<*xpos*>[*+-*]<*ypos*>.
  Negative xpos and ypos will be
  treated as offsets from the right/bottom of the display.

  Examples: **200x100**, **64x64-0-0**, **50x60+100+100**.

Appearance options
------------------

These are optional, and control how **xdeadzone**'s window will
look and behave.

**-i**
  Make window invisible. This is the default.

**-b**
  Make window visible, display as a black rectangle.

**-w**
  Make window visible, display as a white rectangle.

**-n**
  Create window as a normal window, with titlebar and without
  appearing on all desktops. Implies **-w**, but can be followed
  by **-b** for a black rectangle. Cannot be combined with **-i**.

Informational options
---------------------

--help
  Print built-in help, then exit.

--version
  Print the application name and version number, then exit.

ENVIRONMENT
===========

**DISPLAY**
  As usual for X applications: the X server to connect to.

EXIT STATUS
===========

With **--help** or **--version**, exit status is 0 (success).

If there's an error in the arguments, exit status is non-zero (failure).

In normal operation, **xdeadzone** never exits.

EXAMPLES
========

You have a 1920x1080 LCD monitor on the left, and a 1280x1024
one on the right. This gives you a nice 3200x1080 X display... but the
mouse can "vanish", because X pretends the right-hand monitor has
1080 vertical pixels. So there's a 1280x56 horizontal strip "below" the
bottom of the right-hand monitor that doesn't get displayed. If the
mouse moves into this area, the pointer disappears, and it's not
obvious what happened to it.

To avoid losing the pointer, you can run this::

  xdeadzone -se 1280x56 &

...from your ~/.xinitrc (or whatever you use to run commands at X startup).

If you instead have the same two monitors in a vertical arrangement,
with the 1280x1024 one on top, you'll have a 640x1024 vertical strip
of 'dead zone' beyond the right edge of the top monitor. To avoid
losing the mouse there::

  xdeadzone -ne 640x1024 &

If the dead zone were on the left of the top monitor, you'd use **-nw** instead
of **-ne**.
