From f13de9ca1b7c4dd0dd5c08037c6bd53f88ac30f5 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Mon, 18 Jul 2011 21:17:49 +0200 Subject: config: limit the kernel subsystems we look for devices in Don't enumerate/monitor all devices of the system (since that can be quite a few), but limit our search to devices from the "input" subsystem, as well as the "tty" subsystem (to cover Wacom tablets). This should make X start up a bit faster and reduce the number of unnecessary wake-ups of the X server.
