<!--FIXME Compositor Enable compositor on startup necessary to have effects?-->

<para>This module is used to enable and configure desktop effects
for Plasma.</para>

<para>The main part of this page is a list of all available effects grouped 
by <guilabel>Accessibility</guilabel>, <guilabel>Appearance</guilabel>, 
<guilabel>Focus</guilabel>, <guilabel>Peek at Desktop Animation</guilabel>, <guilabel>Tools</guilabel>,
<guilabel>Virtual Desktop Switching Animation</guilabel>, <guilabel>Window Management</guilabel>,
and <guilabel>Window Open/Close Animation</guilabel>.</para>
<para>Use the incremental search bar above the list window to find items in the list.</para>

<para>Normally there is no reason for users to change that, but 
there is a <inlinemediaobject><imageobject><imagedata fileref="configure-effects.png" format="PNG"/>
</imageobject></inlinemediaobject> configuration button to modify the filtering of the list to show 
also those effects.
</para>

<para>The easiest way of installing new effects is by using the built-in
KNewStuff support in &kwin;. Press the <guibutton>Get New Desktop Effects</guibutton> button to open 
a dialog with a list of available effects from the Internet and to install and uninstall effects.</para>
<note><para>Please keep in mind that changing these sensible defaults can break your system.</para>
</note>

<para>Check an effect in the list to enable it. Display information about Author and License by 
clicking the <inlinemediaobject><imageobject><imagedata fileref="dialog-information.png" format="PNG"/>
</imageobject> </inlinemediaobject> info button at the right side of the list item.</para>

<para>Some effects have settings options, in this case there is a <inlinemediaobject><imageobject>
<imagedata fileref="configure-effects.png" format="PNG"/></imageobject></inlinemediaobject> configure button 
at the left of the info button. Click it to open a configuration dialog.</para>
<para>To see a video preview of an effect click on the <inlinemediaobject><imageobject><imagedata fileref="video.png" format="PNG"/>
</imageobject></inlinemediaobject> button.</para>

<para>Some effects are mutual exclusive to other effects. For example one would only want to activate the 
<guilabel>Maximize</guilabel> or the <guilabel>Magic Lamp</guilabel> effect. Both activated at the same 
time result in broken animations. 
</para>

<para>For effects in a mutual exclusive group the &GUI; uses radio buttons and manages that only one of these 
effects can be activated.
</para>

<para>All effects which are not supported by the currently used compositing backend 
are hidden by default (&eg; OpenGL effects when using software renderer).
</para> 

<para>Also all internal or helper effects are hidden by default. These are effects which replace 
functionality from KWin Core or provide interaction with other elements of the desktop shell.
</para>
