xorg & evdev awesomeness
Date: May 27, 2011
with zero configuration for my trackball and keyboard (covered in this post), here is the Xorg.0.log snippet :

[ 7734.495] (II) No input driver/identifier specified (ignoring)
this is so much nicer then having to specify all settings for specific peripherals like we had to years ago.
