Hi all,
Just wanted to add my experience with this. I also have found that my
Synaptics touchpad becomes unresponsive after waking from a suspend. It
isn't restored by a modprobe -r psmouse / modprobe psmouse. The only
thing that restores it is a shutdown (without -r option) followed by a
fresh boot.
I noticed also that, when it is showing this unresponsive touchpad
symptom,
sudo cat /dev/input/event8 | hexdump
produces nothing at all when i move my finger around on the touchpad
(event8 is the touchpad in my system, as shown by
/proc/bus/input/devices). Yet, doing:
sudo cat /dev/input/event16 | hexdump
(which is my usb wireless mouse) does produce output when I move my
mouse around.
I'm not very familiar with kernel, drivers, firmware, etc. I did think
the bit about /dev/input/event8 was interesting though, but I'm not sure
what to do with that information.
If anyone is interested, please feel free to suggest a set of commands
and their output you might want to see, or procedures to try. I hope
this new data point is useful.
Thanks in advance!
Henry

Title:
Touchpad and/or trackpoint stop working after S3 suspend on Lenovo X1
Carbon 6th
Status in linux package in Ubuntu:
Triaged
Bug description:
Ubuntu 18.04.1
Terminology in case we use different terms:
touchpad - just the rectangular touch-sensitive surface below the keyboard
(xinput lists it as Synaptics TM3288-011)
trackpoint - the red thingy built into the keyboard + 3 physical buttons
below the keyboard (trackpoint and buttons are integrated together; listed in
xinput as TPPS/2 Elan TrackPoint)
On September 7th, 2018, Lenovo has issued a BIOS update (v1.30), which
enables proper S3 deep sleep state - users no longer have to patch
DSDT tables to get it. It can be enabled in the BIOS settings. In X1
carbon 6th generation models that have NFC, when laptop wakes from
suspend by opening the lid, in most cases both touchpad and trackpoint
stop working completely. They are also no longer listed when running
xinput command. Sometimes just one of them stops working, usually the
trackpoint. In some rare cases it is possible to bring them back by
using these commands:
echo -n none > /sys/devices/platform/i8042/serio1/drvctl
echo -n reconnect > /sys/devices/platform/i8042/serio1/drvctl
rmmod psmouse
modprobe psmouse
These worked properly when waking up from S2Idle sleep state (had
these in a script that runs after waking the machine from suspend),
but with S3 deep sleep these rarely work and the only way to bring
back touchpad and/or trackpoint is turning off the machine and turning
it on (restart does not help).
I could not find any pattern that would show when the input devices
stop working or start working again using the commands mentioned
above. It's completely random from my perspective.
This is happening on the standard issue 4.15.0-33-generic kernel that
shipped with my Ubuntu 18.04 (with updates), as well as with newer
mainline kernels, such as the newest point versions of 4.17, 4.18 and
4.19 RC2.
This happens regardless of whether "blacklist i2c_i801" is commented
out in /etc/modprobe.d/blacklist.conf or not. It happens regardless of
whether "psmouse.synaptics_intertouch=1" is passed as grub parameter.
Presence of TLP does not make it better, nor worse.
It appears that non-NFC models are not affected. I know at least one
Arch Linux user who has the exact same model, but without this issue.
I'm using synaptics driver (no libinput installed), he uses libinput
and doesn't have synaptics, if that information is of any use.
Libinput does not seem to help.
This forum thread also has more details from users who updated their
BIOS to get S3 suspend: https://forums.lenovo.com/t5/Linux-
