Complete Xorg.0.log

After resuming my system, in some cases my external mouse connected to my docking station does not work in X. The mouse pointer is there, but I cannot move it with my external mouse. The laptop's track point works fine though. Reconnecting the mouse does not help.

I'm using libinput 1.5.0 with xorg libinput driver 0.19.0 on Debian Stretch/Sid.

Xorg.0.log contains this:

Comment 1 Peter Hutterer 2016-10-14 04:46:21 UTC 
I wonder if that's an incarnation of bug 97880, if the device usually works but not after suspend that suggests the fds are messed up
Comment 2 Peter Hutterer 2016-10-19 02:12:03 UTC 
any chance you can try with the patch linked to in bug 97880?
Comment 3 Peter Hutterer 2016-10-19 05:25:45 UTC 
I managed to reproduce the issue while I was trying to debug something else. This is triggered when a device is removed while the fd paused. Specifically:

* vt switch away
* plug a USB keyboard/mouse/... in, this triggers something like:
[ 53688.564] (II) systemd-logind: got fd for /dev/input/event2 13:66 fd 16 paused 1
* when VT-switching to the server now, the device enables and everything is fine

but this sequence here breaks things:

* vt switch away
* plug a USB keyboard/mouse/... in, this triggers something like:
[ 53688.564] (II) systemd-logind: got fd for /dev/input/event2 13:66 fd 16 paused 1
* unplug the device again (nothing in the log)
* replug the device
* vt switch back to the server, device is now broken

fixed with the patches leading up to
