<div class="paragraph"><p>compton could read from a configuration file if libconfig support is compiled in.

<div class="paragraph"><p>compton uses general libconfig configuration file format. A sample configuration file is available as <tt>compton.sample.conf</tt> in the source tree.

"fade" and "shadow" controls window-type-specific shadow and fade settings. "opacity" controls default opacity of the window type. "focus" controls whether the window of this type is to be always considered focused. (By default, all window types except "normal" and "dialog" has this on.)</p></div>

Same thing as above, plus making inactive windows 80% transparent, making frame 80% transparent, don’t fade on window open/close, enable software optimization, and fork to background:

<div class="listingblock">
<div class="content">
<pre><tt>$ compton -bcCGf -i 0.8 -e 0.8 --no-fading-openclose --sw-opti</tt></pre>
