Second monitor not recognized

Hi. I've recently installed Arch on a Lenovo P53 laptop with the following graphic cards:

00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Mobile) (prog-if 00 [VGA controller])
01:00.0 VGA compatible controller: NVIDIA Corporation TU117GLM [Quadro T1000 Mobile] (rev a1) (prog-if 00 [VGA controller])

I'm connected to a docking system (display port) but i'm unable to see content on the second monitor as well.
Running this under Wayland (KDE) i get:
nvidia-settings --load-config-only     

ERROR: Unable to find display on any available system

and if i run it from X11/Xorg server I am able to launch the settings window but on terminal i see there's an error:
$nvidia-settings
ERROR: nvidia-settings could not find the registry key file or the X server is not accessible. This file should have been installed along with this driver at /usr/share/nvidia/nvidia-application-profiles-key-documentation. The
       application profiles will continue to work, but values cannot be prepopulated or validated, and will not be listed in the help text. Please see the README for possible values and descriptions.

Any ideas? i mean i've installed all required (closed-source) drivers for both Intel and Nvidia graphics card.

Thanks in advance!

Re: Second monitor not recognized

Please use code tags for shell IO and don't bump - just edit your post if nobody has replied so far.

Chances are that there's one active output on each crtc, see https://wiki.archlinux.org/index.php/PR … erse_PRIME and please post your xorg log.
You can forget about using an optimus system this way under wayland for the moment.
