Screen Tearing when connecting Monitor in Portrait Mode

General Help
#1

Hello frens,

I recently bought Zorin OS Pro 16 and decided to install them on my Lenovo E14 laptop that I use for work and main device daily and the Lite Pro on an old PC I use as a sidekick.

After the installation and setting the second monitor in portrait mode, I get this tear when I move windows or scroll, it is very annoying and distracting. I searched everywhere, but couldn't find any solutions. It works in landscape though.

I would really like to make it work, as I use it mainly in portrait.

I have only intel integrated graphics card.

Thank you.

I do not use vertical, but I did run a quick search that showed this thread:

The solution offered there actually breaks it even worse. I tried a couple today, this one specifically 2 times and I had to reinstall. One time got login loop with correct password.

#6

have you tried:

sudo nano /etc/gdm3/custom.conf

Comment out WaylandEnable=false by adding a # in front so it looks like #WaylandEnable=false
ctrl+x to exit, then the y key to say yes to save, then enter to save and close.
Test.

It is already commented

Frustrating.
What about avanish's suggestion here (His is an MS Surface notebook)?

I have tried something similar, but instead of "AccelMethod" "sna" I had "AccelMethod" "uxa". And uxa was what was giving me the login loop. I will try it know and hopefully it will work

#10

Nope, it's worse. Both screens flicker and nothing works, mouse, keyboard. Had to unplug the monitor

#11

So the fix from number 7 worked perfect on Pop OS, currently running Pop. But would love to go back to Zorin. They are both Ubuntu based, shouldn't it work the same on both?

#12

The difference is that Pop OS you have tried are build on a newer release than Zorin OS. Zorin OS follows the LTS release.

You could try with newer kernel and see if number 7 then works on Zorin.

sudo add-apt-repository ppa:canonical-kernel-team/proposed -y
sudo apt update && sudo apt upgrade
sudo apt install linux-headers-5.15.*-*-generic linux-image-5.15.*-*-generic

So, the problem will probably be, possible to solve. Just not now. So I am left with choosing, to wait and use Zorin like it is now, or find a temp distro, till I can be sure the problem is solved.

#14

I have updated my post. You can try it, some have luck with it others don't.

EDIT: fixed the right number of kernel

#15

Just ran the commands, everything went well and restarted. Now apparently I do not have any drivers I think, the WiFi is inexistent, the second monitor doesn’t connect and the main display is showed as unknown. Any tips on this? I’m not sure how I can connect it to the web, not even the Ethernet shows up

#16

Then roll back to the current kernel that works best for you:
