Touchpad do not work after suspend

Hi,

my touchpad do not work on my Fujitsu UH552 laptop on wakeup from suspend.
I have added i8042.notimeout and i8042.nomux to boot parameters to get the touchpad to get it to work and that fixes the problem when I boot the computer. But after a suspend the touchpad dose not work.

I have tried synclient TouchpadOff=0 and Xinput disable and enable.

I would be glad for some help,

Fredrik Adolfsson

Re: Touchpad do not work after suspend

One possibility is that the kernel modules are dropping on suspend, and that you need to reload them. I had the same issue with my yoga 3 11 and touch screen modules with suspending.

The way that problem was solved was by creating a custom systemctl service that reloads the modules on resume. I

Make a file named touchpad-fix.service in /etc/systemd/service/

[Unit]
Description=Fix touchpad after resuming suspend
After=suspend.target

[Service]
Type=oneshot
ExecStart=/usr/bin/rmmod <your kernel modules here>
ExecStart=/usr/bin/modprobe <the same kernel modules>

[Install]
WantedBy=suspend.target

And then enable the module with

# systemctl enable touchpad-fix.service

Fingers crossed, good luck!
