Screen tearing on monitors connected to Intel integrated GPU in combination with Radeon R9 285/380 on LightDM

Since my last system update I’m experiencing screen tearing on my monitors that are connected to my internal Intel GPU. I’m experiencing no tearing at all on the monitors that are connected to my dedicated AMD gpu. I’ve got iGPU enabled in the bios so I can use more monitors. I have never had a problem until I recently updated the whole system with -Syu. I’ve tried not using picom, I’ve tried using picom normally, I’ve tried using picom with " --experimental-backend --backend glx" which does make the tearing almost disappear but it’s still there sometimes which is really annoying. This only worked after I downgraded xorg-server to 1.20.9-2.
I’ve also tried to put the following contents into the /etc/X11/xorg.conf.d/20-intel.conf file:

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

But this results in "

[FAILED] Failed to start Light Display Manager on boot.

I’m honestly not sure what else to do, any help is very much appreciated!

This is what it currently looks like

I’m using i3-gaps on 5.4.105-1-MANJARO.

:+1: Welcome to Manjaro! :+1:

  1. Please read this:
    How to provide good information
    and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…

  2. An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
    Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.

  3. In the future, when providing code/output, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text so that the output looks like this:

    Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
    Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
    Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.
    Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
    

    instead of like this:

    Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

    (as that makes both our lives much easier)

  4. No need to do anything right now as I’m an editor here on this site and have fixed it for you already. However, in the future I might not see your post so review my edits by pushing the orange pencil above the post I just fixed. :wink:

  5. As your profile says you’re on kernel 5.4 (we can’t verify as we don’t have an inxi :stuck_out_tongue_winking_eye: ) , have you tried any other kernels already as the Intel drivers are built into the kernel. (The Real-Time version of 5.4 (linux54_rt / 5.4.102RT53_1) would be very high on my list in your case and 5.10 LTS would be next)

:+1:

Thank you for your response. Here’s my output of the inxi command:

I will try some different kernels.

I have tried 5.10 lts and 5.4.102RT53_1 but the issue remains.

As you’ve got an Intel / AMD combo that’s where my knowledge ends, but I’ve added the #amdgpu and #lightdm tags to your question and changed your title to attract different experts than me.
