From 435f27667f84269768efecde34de4af2b2d43376 Mon Sep 17 00:00:00 2001 From: Julien Cristau Date: Sun, 27 Sep 2009 14:45:47 +0200 Subject: config: add libudev input-hotplug backend Add a backend using libudev for input hotplug, and disable the hal and dbus backends if this one is enabled. XKB configuration happens using xkb{rules,model,layout,variant,options} properties (case-insensitive) on the device. We fill in InputAttributes to allow configuration through InputClass in Xorg. Requires udev 148 for the input_id helper and ID_INPUT* properties.
