Hello,
I'm experiencing screen tearing while scrolling and while watching movies and I want to fix this issue.
My pc has a Intel Integrated graphics. I read the whole arch wiki and figured that a fix could be modifying a file called 20-intel.conf (https://wiki.archlinux.org/index.php/Intel_graphics#Tearing here the whole explaination).

Since the "/etc/X11/xorg.conf.d/20-intel.conf" didn't exist I figured out , after half an hour, that the location of this file on my pc was "/usr/share/X11/xorg.conf.d/"
When I went there tho, there was no 20-intel.conf but there were the following files :
- 10-amdgpu.conf
- 10-quirks.conf
- 10-radeon.conf
- 40-libinput.conf
- 70-wacom.conf

This seemed me strange, and for "this" I mean the lack of an intel file since I have an integrated intel graphic and not an amd or radeon, but since I'm not very good at tech I ignored this fact.

I decided that if there was no file I could create the file. Tried with right click to create a new text but it didn't work. After 1 hour I managed to learn the sudo nano command from terminal and I created the exact file that the Arch wiki provided me as a fix (fun fact, a quarter of hour passed to understand how to save the file created in sudo nano from terminal)
I restarted, opened firefox ( I've tried both webrender and layers.acceleration.force-enabled).
It's not a problem of firefox I think (before I had ungoogled chromium and it happened there too), it happens in all the apps (VLC included), even in the system settings while scrolling applications. It must be related to some configuration of the system I think. and screen tearing was gone. Perfect one may think, the downside is that the entire system now seem to go at 3 fps and all program didn't respond (this program isn't responding wanna close it? window appearing everywhere).
To fix it I managed to restart pc and at login I ctrl+alt+f4 and removed the 20-intel.conf file I created by command line.

Now system is working as usual, but I still have screen tearing and I'm frustrated as hell cause I've not been able to fix it by myself.
Hope you guys can help me.

I'm not an expert on screen tearing but I did find a few articles that may help you.:)


It's possible to minimize screen tearing with a little tweak to the X11 configuration. However this option may not work always, specially with Intel Atom or Celeron CPU's inbuilt graphics.


If you’re running into issues on your Gnome Shell desktop environment, the best thing to do is to switch to the Gnome Wayland session, instead of running the old X11 mode.

I was just remarking earlier today that the time invested in learning nano is well spent. This isn't an answer to your question, but I'd suggest spending some more time poking at nano. Once you do that, your Linux days will get easier. When you want to edit a file, you'll 'sudo nano /path/to/file' and just be done with it. Take a look at 'man nano' and you'll soon see more advantages such as 'sudo nano -B /path/to/file'. That'll save your bacon if you mess up, as '-B' means that it creates a ~filename.txt backup automatically.
