My problem is in relation to the message in the image below. How can I activate advanced mode and synchronization?

PRIME displays means those are connected to the intel/amd igpu, not the nvidia gpu thus can’t be controlled by nvidia-settings.
PRIME Synchronisation can be enabled using the kernel parameter
nvidia-drm.modeset=1
(Might not be working on 5.5/5.6 kernels)

hello @generix, thanks for the help!!

I forgot to mention it before, but my notebook is managed by Optimus notebook so Ubuntu’s gpu-manager is taking care of xorg config.

And as you said, my monitors are being managed by the intel card. The above command shows this !!

I tried to put a nvidia-drm.modeset=1 in /etc/default/grup, but there was no screen.

What’s the latest version of kernel that is working?

Would there be another way for me to manage my monitors via nvidia?

I change the nvidia-drm.modeset=1 to the beginning of the file and synchronization now is On!! But it’s not yet possible to control via nvidia-settings.

My kernel: 5.4.0-24
What’s the latest version of kernel that nvdia working?

Would there be another way for me to manage my monitors via nvidia?

Like said, PRIME displays can’t be controlled by nvidia-settings since they’re not connected to the nvidia gpu. Expected, no way around it, nada.
Simply use your DE’s monitor manager to arrange/adjust monitors

Ok. Thanks for your help @generix!!!

I have the exact same problem. My laptop only lets me use FHD on my 2K monitor. And also it is marked as PRIME display. What can i do? Any help is welcome :)

Hello,

I have an Nvidia NVS 810 graphics card, running on Ubuntu 24.01 LTS, with six monitors connected to the card. However, my Nvidia Settings Manager shows six monitors plus three additional ones that I don’t have. The settings indicate that three monitors are not activated, 3 activatet at screen 0 and three are marked as Prime.

I am unable to move any of the three Prime monitors. Additionally, I cannot save the configuration to the xorg.conf file because I need to generate one first. When I use this file, only two or three displays are recognized. This is quite frustrating as I want to use all six displays.

Could it be that RandR and the Nvidia settings are incompatible and causing this issue?
Why 3 are Prime althoght I have every display connect to GPU. I see 3 at GPU0 and 3 at GPU 1 and 3 prime that makes no sence.

Kind regards, Katharina
