            Bug ID: 89296
           Summary: libinput: Xserver crash with suspend/resume
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: fourdan at xfce.org

I've noticed that each time I suspend/resume my laptop, I was losing my X
session.

Using xorg-x11-server-1.16.3 with libinput-0.11.0 and
xf86-input-libinput-0.7.0.

A quick look at the logs reveals that the Xserver crashed because of libinput:

(/dev/input/mouse

This is probably xfce4-settings daemon trying to access a device, as killing
the xfsettigsd before suspending the laptop avoids the crash.

Yet, even if one of the client is misbehaving (I am not entirely sure how yet
though), the libinput/xf86-input-libinput should not crash and handle the
client nicely.
