Screen tearing optimus laptop - Asus TUF A15 2021

mario156090 · December 17, 2021, 11:54pm

Goodnight:

I have tearing problems with my RTX 3060 mobile graphic, I use the Arch Linux operating system and I have the latest drivers available to date.

I have already placed a file in /etc/modprobe.d with the content options nvidia-drm modeset = 1 and confirmed that the query in / sys / module / nvidia_drm / parameters / modeset returns a Y so theoretically prime sync should be activated, however, I still keep tearing. Please if someone could give me a hand with my problem. Thanks a lot.

According to the log the amd is primary gpu, the nvidia is only on-demand.
Does tearing also occur if nvidia is primary?

I test too with another kernel version, in this new case with linux-lts with the same problem.
I test too with another Desktop Environment, in this case with plasma desktop with the same problem.

This looks like the amd gpu is not emitting any vsync signal. Please switch back to on-demand mode for the nvidia gpu and have the amd gpu primary.
Looking at the xrandr output from your first log, there’s a 144Hz panel running at 60Hz. When back on amd gpu, please switch to 144Hz and run glxgears on the amd and check whether it’s then limited to 144Hz.

mario156090 · December 18, 2021, 3:41pm

Thanks for replying again.

If I set the screen at 144hz in on-demand mode, in fact there is a limitation of 144 FPS. If in on-demand mode I set it at 60 hz there is also a limitation at 60 FPS. With all these details, always with nvidia there is that tear in games.

Now I have realized these details, when I am in nvidia mode my screen application offers me these settings:

As you can see, it offers you configurations with vsync.

Now when it’s in on-demand mode I only see two settings available and neither of them offer vsync.

It’s good to mention that the tearing is only felt in games that run on nvidia. I have not tried many games but I think I could try another. For now I am talking about DOTA2.

The results in GLXGEARS always offer an FPS limitation as I will show in the following images.

Set screen to144hz with primary AMD GPU:

Set screen to 144hz with NVIDIA on demand GPU:

Set screen to 60hz with primary AMD GPU:

Set screen to 60hz with NVIDIA on demand GPU:

PD: Prime run is only a script for run with nvidia:

So, having observed this we could say that the vertical sync is working correctly. Even on the desktop or watching videos using the primary I do not see any tear, but just open the game with NVIDIA and the tear appears.

If I open the same “DOTA2” game with the primary AMD the tear disappears.

So my suspicion about the amd gpu was wrong, it’s running vsync’d. Then nvidia gpu in on-demand mode, the frames will just be limited by the compositor but running unsynced.
Please switch back to nvidia as primary but use the amdgpu driver instead of modesetting, then check if glxgears is still running unsync’d.

mario156090 · December 18, 2021, 5:02pm

AMD is using modesetting as default controller, now with nvidia as primary FPS is not capable with screen resolution:

In this case 144hz:

I will check how I can change default controller for my AMD device. @generix do you want to say amdgpu-pro?

I checked and I using amdgpu and not modesetting.

generix · December 18, 2021, 6:07pm

I meant the Xsrevr driver (DDX). You have in your xorg.conf
Section “Device”
Identifier “integrated”
Driver “modesetting”
BusID “PCI:5:0:0”
EndSection
Please change
“modesetting” to “amdgpu”
Don’t install amdgpu-pro, this will break the nvidia driver.

Ok, this is my xorg.conf config:

PD: In this case I’m using third party app called optimus manager for create this archive.

I do know how I can do this Manually.

Edit:

Wells aparently the problem were in amdgpu config because after add the option tearfree and amdgpu the tearing is fixed.

How I can create this file manually?
