Hi Vidak64, I managed screen tearing with intel chips like what is written here in this thread

If something is unclear about the procedure please ask and always post your hardware
inxi -zv7
from terminal

I used to add below to my /etc/X11/xorg.conf.d folder.
Name the file 20-intel.conf and add the below to it..

Section “Device”
Identifier “Intel Graphics”
Driver “intel”
Option “AccelMethod” “sna”
Option “TearFree” “true”
EndSection

———————————

As I do for amd and antiX-21

20-amdgpu.conf

Section “Device”
Identifier “AMD”
Driver “amdgpu”
Option “TearFree” “true”
EndSection

Great! Exactly, what worked?

Philosophers have interpreted the world in many ways; the point is to change it.

antiX with runit - leaner and meaner.

Was it caprea or koo suggestion that worked for others with older intel video chips?
Vidak64, please state what worked so others know and this can get marked solved.
Thanks koo for sharing will try it as I have several systems with that issue, just
haven’t had time to mess with them much.
I have several with Intel 845, 855, 865, 915, 945, 965, and HD ones.

With the intel version you may need to change AccelMethod from sna to uxa. I’m not sure of the difference anticapitalista may know why but sna worked for me.

And with nvidia I used to run sudo nvidia-setting and turn on full pipelines to end the screen tearing.

Below suggestion from Koo caused boot fail, no device found on my intel test box.
will try again shortly with accel method set to uxa.
Will also look how MX updated to 21 is setup on an identical device, no tearing on that one.

I used to add below to my /etc/X11/xorg.conf.d folder.
Name the file 20-intel.conf and add the below to it..

Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
EndSection

What part of it worked for you?

[ModdItMember]

First please be careful, on some hardware this will result in boot failure.
Confirmed by User experience.

Keep a live stick handy so you can delete the change on any failure.
As I am unsure on rectification, where encrypted file system is concerned
it may not be worth the risk.

RE posts In this thread regarding screen tearing
code addition to /etc/X11/xorg.conf.d folder.

The code was mangled by the forum software, below code should now work correctly..
i also had to learn, We must use the code tag in front of and after
code to show code and often urls in a usable form.

For Intel Graphics devices

using sudo and your editor of choice create a file within /etc/X11/xorg.conf.d
folder, name it 20-intel.conf add below code. Save, changes only take effect after a reboot.

Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
EndSection

For AMD Create a file within /etc/X11/xorg.conf.d folder, name it 20-amdgpu.conf
add below code. Save. changes only take effect after a reboot.

Section "Device"
Identifier "AMD"
Driver "amdgpu"
Option "TearFree" "true"
EndSection

On AMD, and with my specific desktop hardware the result is not perfect, but display
much improved.

Are you using compositor?

I used to have screen tearing with modesetting driver. Used picom and no tearing. Didn’t need xorg config files. This is on old intel iGPU.

I have this line in ~/.desktop-session/startup

picom --backend glx --vsync &

Hope this helps. Cheers !!
