For this, i need to use the xf86-video-intel package no?
i915.enable_psr=0 as kernel boot option for the driver will disable some power saving option that can cause issues with iris hardware… see here for other possible options:
https://discovery.endeavouros.com/intel-gpu/intel/2021/03/
I just tried this, and still happens when I do scroll 
I tried with a fresh instalation with the latest kernel (6.0.2) and removing the xf86-video-intel , and this still happens: https://photos.app.goo.gl/yxmEQ39PcXvJidu76 See what happens when I do scroll, are you using the latest LTS?
I just tried the i915.enable_psr=0 in the kernel, and update picom to use the backend glx, and the same happens :‘( Sincerelly, I’m exhausted to look for different options or solutions and read in different forums :’(
no the in kernel mode setting driver uses this option too. but like always do not test to many things at the same time 
Yes, I tried the picom config before, and nothing.Then I added the i915.enable_psr=0 to grub using the steps here https://discovery.endeavouros.com/intel-gpu/intel/2021/03/, and nothing
there is also this:
https://wiki.archlinux.org/title/Intel_graphics#AccelMethod
where it says “uxa” mode can help
If I set the AccelMethod to uxa the screen doesn`twork, after load finish like a black screen and I can’t do nothing 
@jmanuelrosa
Have you tried the following kernel parameters. Try each by themselves one at a time. Se if any difference.
intel_idle.max_cstate=1
i915.enable_dc=0
could we see a boot log?
journalctl -b -0 | eos-sendlog
or from eos-log tool…
I just tried both, each by themselves one at a time, and nothing, the problem with the scroll persists (I removed the xf86 driver before). I don’t know if I’m doing something wrong:
- I edit
/boot/grub/grub.cfgfile adding the parameter at the end of theGRUB_CMDLINE_LINUX_DEFAULT - run
sudo grub-mkconfig -o /boot/grub/grub.cfg - and reboot the system
is it ok?
The boot log: https://0x0.st/ow7T.txt bt the problem is not in the boot, is with the scroll in some apps, for example, in VSCode, Chrome, etc but not in Firefox
yea but… while booting graphics driver are loaded and settings will get sorted
I just try out disable vsync on my ancient intel ThinkPad and this vertical tearing in watching videos is gone…
Do you try that ?

and indeed as i was thinking there is a “crash” trace on your GPU and driver:

If I’m not wrong, for this configuration I need to install xf86-video-intel right?
there are two drivers one is inside kernel tree the other came with this package both providing drivers only differently…
I just tried with the xf86-video-intel package installed and removed, and in both cases, chrome doesn’t work, not responding
having vsync disabled? and using exactly what options on kernel boot line?
It is indeed a bit tricky if you are not used to tinker with such things…
But it is needed to test one thing at a time and if it is not working remove that again before going to start the next …
do you actually tried lts or not?
I would recommend in general to have LTS kernel installed aside from main one to try it if issues happen… in a lot of cases it is simply some kernel regression stuff happening and it will get solved with one or the other kernel package update…
Yes, when i try something, and doesn’t work, I rollback all changes and start from 0
I just try with Linux Kernel LTS 5.
~/.drirc
<device screen="0" driver="dri2">
<application name="Default">
<option name="vblank_mode" value="0"/>
</application>
</device>
and it’s working !
With latest linux kernel works veeery slog and laggy but with LTS is working well (a little tearing but I can assume it)
