Screen tearing on XFCE AHS

[danielson]

Have tried compositor with Compton, Xfwm and none at all, still getting screen tearing in Firefox and Vivaldi.

with that graphics chip and processor there isn't much reason to use the ahs stuff. I know, because I also have an ivy bridge. I don't get the screen tearing though, at least not with a single monitor. I do with a second monitor. switching to the "intel" xorg driver (mx-tweak->other tab) help the screen tearing for me. the setup for that driver includes utilizing a "tear free" option for the intel graphics driver.

@dolphin_oracle - much better, thanks! :)

Smoother on Vivaldi than Firefox (smooth scrolling issue there i suppose).

[dolphin_oracle]

I'm glad that's better.

I know my machine works ok with the 5.14 kernel, except for suspend, which doesn't work at all. things work better with the 5.10 kernel. I know there are changes to the i915 drivers in the 5.14 kernel. things aren't better on the 5.15 kernel either.

@dolphin_oracle - think your tip also helped to resolve an oustanding issue i had (that others don't seem to have), namely, a momentary "hic" in the sound while listening to Ytube for example. Something that would happen on irregular time frames from a few minutes to more.

Seeing that (as it often happens) i'm the marginal one to report such a thing, i didn't post a new thread about it.

Btw, love the work you guys are doing! :)

Nice to see you and the other devs doing so much firefighting because kernel devs and desktop devs keep forgetting the basic rule: "If it ain't broke don't fix it". Keep up the good work!

P.S. I did find a way to return from suspending with the ahs/5.14 kernel on intel. It's a bit convoluted but at least it proved all the data was still there. I pressed (e.g) CTRL-ALT-F3, logged on the resultant text screen, and hibernated from there. On reboot, I was able to press CTRL-ALT-F7 and my screen had returned. So at least we know that the problem purely relates to the screen layout.

I literally solved all my major XFCE AHS problems by zapping it and installing standard XFCE.

the solus guys just announced they are holding off on xorg and kernel updates because of issues like these.

Did this part as suggested here and rebooted:

... go to “/usr/share/X11/xorg.conf.d” and add one of the files below for your graphics card.

For Intel drivers edit or create a file called “10-intel.conf” and add the following then reboot your pc:

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

No more screen tearing! :)
Sounds like a name brand for shampoo...
