View Full Version : [ubuntu] Touchpad unresponsive after each suspend after 14.10 upgrade

Just upgraded to 14.10 from 14.04 through the software updater tool. No hiccups during the upgrade, but I noticed that now when I suspend and resume, my touchpad becomes unresponsive unless I restart. My external USB mouse works fine either way, just the touchpad does not work. I have an acer aspire E5-571 (link here (http://www.newegg.com/Product/Product.aspx?Item=N82E16834314539)).

Any thoughts?

Hi there,
I'm having similar problems (on the same laptop). Unfortunately, I don't have access to my laptop at present, but I found this (https://help.ubuntu.com/community/SynapticsTouchpad). I'm going to try it out as soon as I get home. The part which I think is of most interest:

Touchpad not working after login

This usually happens when you disable your touchpad and then suspend your computer. To fix this just run this command:

gconftool-2 --set --type boolean /desktop/gnome/peripherals/touchpad/touchpad_enabled true
If nothing else works, please see the official Ubuntu touchpad debugging article (https://wiki.ubuntu.com/DebuggingTouchpadDetection).


I hope this helps!

Ah, thank you for the reply. Unfortunately, I think this only works if you manually disable the touchpad prior to suspend, with the common Fn + F7 on most laptops.

I tried that command to no avail in my case. I guess we gotta keep trying!

Hello,
same problem here :/ I have an Acer Aspire E5-471 with Elantech touchpad and happends exactly the same, everything works fine until I suspend and resume the touchpad totally dies. I have no idea how to solve but if I can help in something like posting more info tell me, i'll keep searching anyway.

For now I've downgraded back to 14.04 as this is quite an annoying problem for me (I suspend and resume my laptop all the time) but if someone can figure this out I'd very much like to mark this thread as solved :)

Did anybody find a good solution or workaround for this annoying issue? I have of course tipped the "beeing affected" button in launchpad, but there are only 9 people beeing affected, can this be???

I've just tried the script mentioned here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1393079/comments/7 (copied below) with a positive result.

This is what I did to fix this for me:

# sudo touch /etc/pm/sleep.d/10_touchpad
# sudo chmod 755 /etc/pm/sleep.d/10_touchpad

Then edit the file 10_touchpad and paste the following into it:


#!/bin/sh
case "${1}" in
resume|thaw)
rmmod hid_multitouch
modprobe hid_multitouch
;;
esac

mitya-2 (http://ubuntuforums.org/member.php?u=1863916)'s suggestion worked on my Lenovo Yoga. I tested it several times. The mouse and trackpad click events are now working after resume from suspend.
Thank you very much.
