Touchpad disables after suspend for longer periods ( Yoga slim 7)

Support

Hi all,

I have a Lenovo Yoga slim 7 with Manjaro 20.2 KDE. The laptop had this issue that after suspend the touchapd would stop working. I found a fix in the following thread:

It appeared to work for the most part, but I noticed that when the laptop remains suspended for a longer period, for example during the night, the touchpad either doesn’t work at all or works for a few seconds and disables again. After which I have to run the script manually or reboot the computer for it to work. When I check the status of the service using:

systemctl status restart-touchpad.service

It appears to be working and be executed right when I woke the computer from the suspend. the above command returns:

● restart-touchpad.service - Restart Touchpad
     Loaded: loaded (/etc/systemd/system/restart-touchpad.service; enabled; vendor preset: disabled)
     Active: inactive (dead)

дек 26 11:08:32 spasimir-82a2 systemd[1]: Starting Restart Touchpad...
дек 26 11:08:32 spasimir-82a2 EnableTouchpad.sh[113680]: Restarting Touchpad just in case

дек 26 11:08:32 spasimir-82a2 systemd[1]: Finished Restart Touchpad.

The fix appears to work without issues for shorter periods of time, if it is only a couple of hours or so. Any ideas how this can be resolved? Let me know what info I can provide that will be helpful in resolving this, it appears touchpad issues are common for this laptop.

This is your Touchpad. I have another one though (Lenovo Yoga Slim 7 14ARE05 with 4800U 82A2), even though besides that I have exactly the same notebook. So I can’t give any advise besides what I could find on the internet.

Hi linos,
Thank you for the comment. I actually switched from KDE to GNOME because of the tiling features available in it. The touchpad actually works much better and has stopped only once since then although every time I wake it from suspend a disable touchpad message appears.

7

I also have this “disable Touchpad” icon after resuming from suspend. It’s not quite charming to look at, but as long the touchpad kicks in afterwards its fine.

8

Yes indeed. Interesting why it didn’t work with KDE I thought that the hardware would perform the same no matter the DE.

9

Are you sure, that you have been testing both on the same kernel?

11

I tried a few different kernels on KDE, and I dont think it worked on any of them. If I remember correctly this includes the one I am currently using in Gnome as well. I am running Kernel: 5.10.2-2-MANJARO currently. But I don’t remember for sure so if someone has this issue maybe they can give it a shot.
