Lenovo Yoga 7 14ARB7 Touchscreen randomly not working

Hardware Support

Hi, its my first time posting and im quite new to Linux.

Anyway, after I tried Zorin OS on my desktop, I installed Zorin OS 18.1 Core on my Lenovo Yoga 7 14ARB7 and noticed that the touchscreen randomly stops working. Touch and stylus inputs are not being registered while the rest of the system (using mouse and keyboard) works completely normal. Touchscreen funcionality resumes after putting and waking the system to/from sleep. I kinda need my laptop for taking notes at uni and I really don't want to go back to Windows. Any help/idea is appreciated.

Welcome to the Forum!

  • Are Secure Boot and Fast Boot on BIOS disabled?
  • If Windows is still installed: Is Fast Start-Up in Windows disabled?
  • Does Zorin run in Wayland or X11? You can check that with the Terminal Command echo $XDG_SESSION_TYPE

  • Secure Boot and Fast Boot are both disabled
  • Windows is not installed
  • Zorin runs Wayland

Then, I would suggest first to try it with switching to Xorg. Go to the Login Screen. click there on Your Profile so that the Password Field appears. When it is appeared, You should see a Gear Icon in the bottom right Corner. Click on it and choose the Option ''Zorin Desktop on Xorg'' and then log in.

Switching to Xorg unfortunately doesn't resolve the issue.

I spent the night tinkering and reinstalling diffrent OS a dozen times. Reinstalling Zorin OS 18.1 didn't fix the issue. Ubuntu 26.04 seems to work without any issues, but I don't like its appearance. I also tried Kubuntu 26.04, also having the same issue as Zorin OS 18.1. These findings might narrow down the possible causes.

Edit: Kubuntu seems to work. After that one occurence it worked fine.

Zorin OS is build upon Ubuntu 24.04, so with Ubuntu 26.04/kubuntu 26.04 they have newer libraries in the system, which would explain it work on them.

Is there a way to work around that? Otherwise I'll have stick to Ubuntu I guess :confused:

You could try:

sudo apt install xserver-xorg-input-evdev
xinput-calibrator

Need to be logged into xorg.

You could give Ubuntu with Gnome Extension a similar Look to Zorin. You would need Dash To Panel and ArcMenu to get the default Zorin Layout. For the Theme, You would have to look for something similar.

You could theoretically try to copy the Zorin Themes in Live Mode on a USB Stick and then move it to Your Ubuntu Install but if the Themes work with the newer Gnome Version is questionable.

The Problem still persists. I think I'll stick to Ubuntu for now. But thank both of you for your help!
