Subject: Xuser has no permissions for event devices (no keyboard and mouse in X)
Date: Tue, 02 Apr 2013 14:08:59 -0700	[thread overview]
Message-ID: <515B48EB.6040209@linux.intel.com> (raw)

Current master atom-pc build + pending 3.8 kernel update us using
rootless X, but X fails to open the event devices. Do we need some kind
of default group permissions for the /dev/input/* devices?
