From 740daf5c8b2908211b4ae1ad2c9353688bb1e2f9 Mon Sep 17 00:00:00 2001 From: James Knight Date: Mon, 22 Jun 2015 12:15:37 -0400 Subject: support background setter for specific screen The following adds the ability, when using `feh` as a background setter, to use a specific Xinerama screen to render a provided image. Along with the provided '--bg-*' option, the '--xinerama-index' argument will be used to identify the index of the detected Xinerama screen to use.
