Video-hybrid-amd-nvidia-prime no HDMI on Dual-GPU Laptop

Yes, that seems to be the right configuration. Unfortunate that it doesn’t work, but I have no other ideas. It seems you need to stick with the other configuration.

Using the earlier configuration of Option "PrimaryGPU" "yes" for the dGPU gives a somewhat low refresh rate on my primary display (inbuilt). I’m not sure if I’m using the right terms, but it does not feel right and is jagged and not smooth as normal.

Is there a fix for this issue?

I’d suggest trying optimus-manager as it provides a more flexible way to configure this all.

@pobrn
Thank you very much for all your help!

Can only agree with @pobrn on trying optimus-manager. You should definitely give it a go.

Using optimus-manager gives the exact same problem.

I’m not sure if I’m using the right terms, but it does not feel right and is jagged and not smooth as normal.

It does make it easier to switch between modes though.

An interesting thing is that this scheme of going “dGPU only for getting the HDMI to work” is present in Pop-OS’s system76-power package which gives it in a way very similar to optimus-manager (I susupect system76-power to be playing with the conf files as well).

Upon using that mode in Pop-OS, HDMI works fine and also there is no jagged-ness.

I have both Manjaro and Pop-OS installed right now and I prefer to run Manjaro full-time. Which are the config files I must compare/copy over and reproduce the desired behavior in Manjaro as well.

Which mode? “nvidia”? Can you post the output of inxi -Gazy and xrandr -q on both Pop!_OS and Manjaro?

I do not have access to my monitor as of the time being. But I guess that would not be important for these logs, as the primary display is the one in question.

Pop!_OS

I think it is. This is the output of optimus-manager --status:

Optimus Manager (Client) version 1.4

GPU mode requested for next login : no change

Can you also post the output of xrandr --verbose | grep PRIME and cat /etc/X11/xorg.conf.d/10-optimus-manager.conf on Manjaro?

What’s in /etc/optimus-manager/optimus-manager.conf?

cat /etc/optimus-manager/optimus-manager.conf

I think I have managed to solve it!! :partying_face:

Here it says we need to enable Prime Sync by enabling the DRM Kernel Modesetting (‘e’ in the grub menu and adding nvidia-drm.modeset=1 before boot).

After logging in, following from here, running xrandr --output eDP-1-1 --set "PRIME Synchronization" 1 solves the issue.

Although, xrandr --verbose | grep PRIME still reports PRIME Synchronization: 0 even after enabling it. :thinking:

If I recall correctly, this is a known issue, that is, xrandr --verbose still reports 0 even though it is enabled.

Now that the screen tearing issue is solved too, I’d like to summarize this thread into a single post and have it at the bottom/at the “how-to” section to help anyone facing similar issues.

Please let me know if there are any “best practices/methods” to follow related to laptops/hybrid GPUs with HDMIs so that I can put it up in that as well.
