     <title>Wacom Tablet Settings</title>
     <para>
         The tablet &systemsettings; module handles all setting for your graphic tablet. All tablets supported by
         the <ulink url="https://linuxwacom.github.io">&Linux; Wacom driver</ulink> project are handled by this settings interface.
         Make sure your tablet is detected either via xorg.conf or udev and works in general. Refer to the <link linkend="detection">tablet detection</link> section for more information.
     </para>
     <important>
         <para>
             The <application>xf86-input-wacom</application> driver must be installed on your computer and <command>xsetwacom</command> must be available in order to make this module work correctly.
         </para>
     </important>
     <para>
         The module is split into various tab pages that handle all aspects of your tablet and the pen:
         <link linkend="tablet-profiles">Profiles</link>,
         <link linkend="tablet-general">General Information</link>,
         <link linkend="stylus">Stylus Settings</link>,

         <link linkend="pad-mapping">Pad Mapping</link> and
         <link linkend="touch-mapping">Touch Mapping</link>.
     </para>
     <sect1 id="tablet-profiles">
         <title>Profile Management</title>
 
         <para>
             This is the small drop down box with the two buttons next to it. You can create new profiles and delete already existing ones.
             Each profile is saved and specified for the currently connected tablet. If you create a new profile, it automatically creates one
             with the default settings as returned by the driver.
         </para>
 
         <para>
             Here you can specify different profiles for your settings.
             For example if you like to have a different behavior of the pen when you use it
             as a mouse replacement for your day to day work or using it as pen to draw something.
         </para>
         <para>
             Each profile can be changed on the fly and directly changes the behavior of your tablet input.
         </para>
         <note>
             <para>
                 The <link linkend="kded">kded tablet daemon</link> must be running in the background to be able to change the profiles and apply them to the tablet.
                 All the work is done by the daemon. The &systemsettings; module just change the profile settings for it.
             </para>

             Shows some general Information about the detected tablet.
             Beside the name and company of your tablet an image is shown and all detected input devices are listed.
         </para>
 
         <note>
             <para>
                 The tablet must be connected and the <link linkend="kded">kded</link> must be running to allow the module to work correctly.

         <para>
             In addition to the tablet information the general tab allows to set various global shortcuts. Each shortcut allows to dynamically
             change the options for the current connected tablet.

         <para>
             The pen that is used together with the tablet has two different sides, the main side is called stylus the other end is the eraser.
             In this tab you can change any aspect of the pen from the button assignment to the pressure curve and threshold.

                 The slider allows to alter the threshold of the eraser. For a more fine grained setting of the pressure it is possible
                 to alter the complete pressure curve in the <guilabel>Edit Pressure Curve</guilabel> dialog.

             <para>
                 If <guilabel>Tap to execute action</guilabel> is enabled the stylus must be in contact with the tablet in order to allow the button action
                 to be executed. If this option is disabled each button action works also when the stylus is hovering above the tablet.

             If udev does not handle the detection add the tablet to your <filename>/etc/X11/xorg.conf.d/50-tablet.conf</filename> file (create it if it does not exist) and restart the x-server.

         <para>
             In case of a serial device (Tablet PC and such) check if <command>xinput --list</command> lists your input devices (Stylus/Eraser/Pad).

         <para>
             Hotplug support is only available if the tablet is found via <application>Solid</application> and its notification API.
         </para>
         <para>
             <application>Solid</application> checks if the value for the entry <command>input.x11_options.Type</command> is <command>pen</command>,
             <command>stylus</command>, <command>eraser</command> or <command>cursor</command> or if the value for the entry <command>input.x11_driver</command> is <command>wacom</command>.
         </para>
         <para>

     <title>Tablet plasma applet</title>
     <para>
         The tablet applet makes it possible to change the available profiles on the fly. Furthermore you can change the pad rotation and switch between absolute/relative mode
         of the stylus/eraser regardless of the current profile settings.
     </para>
     <para>
         It is not necessary to add the plasmoid for this module to work. The default profile will be activated by the  <link linkend="kded">tablet daemon</link> as soon as it
         detects your tablet even if the plasmoid is not used. The plasmoid is just a visual helper to switch easily between the profiles.
