Lenovo T440 trackpad issue: sometimes not working on resume from sleep .. workaround (or maybe fixed?)

Not experienced any on this one so far. I don’t know if this would make any difference but I have tapping disabled; I use the full click on the trackpad.

Ok -thx for that info.

I should update to say I did need to re-apply the modprobe stuff on first resume with the new 5.8 Kernel but not had do so since, so far.

Update:

This no longer works with the new 5.10 kernel.

Get a FATAL: error as the module is now integrated in the kernel. Had to revert to 5.9 but this worries me as this series will be out of support in due course and, although I can use a mouse THIS ISSUE PREVENTS SLEEP which is a show-stopper. When this occurs I have to shut down before I can put it in the bag which is not acceptable. I will need it for a service call tomorrow, for example.

If they haven’t fixed the bug, why on earth did they integrate it?

Any workarounds for this?

You can put a script in /lib/systemd/system-sleep/touchpad and chmod 755 and it’ll run on wake.

Hi chovy,

I am also using a T440s with latest version of Manjaro and also have the issue that my touchpad isn´t working anymore after sleep. It would be great if you could specify the content of the script as it is not clear for me what to add.

Thanks and regards

The kernel fix worked for me. Details below.

My machine:

OS: Manjaro Linux x86_64 
Host: 20KGS03800 ThinkPad X1 Carbon 6th 
Kernel: 5.10.34-1-MANJARO
DE: Plasma 5.21.4

Open /etc/default/grub with a text editor of choice (e.g. sudo vim /etc/default/grub). Append psmouse.synaptics_intertouch=0 to GRUB_CMDLINE_LINUX_DEFAULT=.
Reboot. Then close the lid or enter sleep mode manually and resume. The touchpad should work immediately (and so should the shoulder keys).
