Two finger scrolling not working after suspend

[Séverin Lemaignan]

When waking up my laptop, two finger scrolling is not working anymore.

Running:

$ modprobe -r psmouse
$ modprobe psmouse

restores the functionality.

Status changed to 'Confirmed' because the bug affects multiple users.

[rathboma (beekeeper-studio)]

I have this exact issue.

I'm running a Thinkpad X1 Carbon 5th generation. Sometimes two-finger scrolling half-works, sometimes it breaks entirely.

Everything was working fine until a software update at the end of September.

I had the same issue, and got it fixed by using the following comment:

[Ishuah Kariuki (ishuah)]

I'm running into this issue too

The solution detailed here doesn't solve my issue --> https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1722478/comments/72

I'm running Ubuntu 18.04 on a Thinkpad P52s.
This solution works for me (I just have to run it every time I get back to my computer from a suspended state):

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1722478/comments/24

      $ sudo modprobe -r psmouse
      $ sudo modprobe psmouse

[regis paquette (regis74)]

I have the same issue on 18.04.3 on x1 carbon gen 5th
the below solves it too:
      $ sudo modprobe -r psmouse
      $ sudo modprobe psmouse

I got this issue on Ubuntu 20.04 too... on this laptop I had a similar problem on the 19.10, the touchpad didn't work at all after resum from suspend, i used to fix that calling

sudo rmmod i2c_hid
sudo modprobe i2c_hid

and it works too on this issue on 20.04, shall we provide some more informations to solve the problem at its root?

[aphid (aphid)]

thrantir's solution works for me in 20.04, is there a way to make this automatic on wake?

[Javier (javidlg)]

I have the same issue on my lenovo E480, so annoying! I'm was used to accept

      $ sudo modprobe -r psmouse
      $ sudo modprobe psmouse

as a solution, but I'm running into this issue since severals years ago :(

Distro: Elementary OS 5.1.5 Hera

Kernel: 5.3.0-53-generic

[Matthew Ross (mattross65-1)]

I'm using 20.04 Ubuntu with Gnome desktop and have the same issue. As a fix I used code mentioned above Eg "modprobe psmouse" as the solution.

I placed the following code in a file called "touchpad"

     #!/bin/sh
     $sudo modprobe -r psmouse && $sudo modprobe psmouse

To do that I used "sudo gedit" and navigated to the directory and put the text in.
I then ran the below command in the terminal to make it executable

      chmod +x /lib/systemd/system-sleep/touchpad

To my understanding (which is limited) anything in that directory runs when the computer wakes up so the two finger option starts again automatically. The "touchpad idea came by varying the code on the below site with the solution mentioned above.

It appears to work reliably so far, and while it is not a true fix to the bug, it might further assist in the meantime.. Cheers M.

I am also having this problem on a Thinkpad T450s with
OS: elementary 5.1.7 Hera (built on Ubuntu 18.04.4 LTS)
Kern: Linux 5.4.0-70-generic

The driver "restart" solution (sudo modprobe -r psmouse && sudo modprobe psmouse) worked for me as well
