NVIDIA KMS freezes system with multimonitor setup

I have a strange issue and cannot find any answer to my problem, so I hope someone can help me out. I

PC: Lenovo Legion 5
OS: EndeavourOS Linux x86_64
Kernel: 5.17.1-arch1-1
CPU: AMD Ryzen 7 4800H with Radeon Graphics (16) @ 2.900GHz
GPU: NVIDIA GeForce RTX 2060 Mobile (nvidia-dkms 510.60.02-1)
WM: awesome

I have 3 external monitors connected to my laptop, when I set nvidia-drm.modeset=1 (and all the other nvidia nvidia_uvm, etc.. modules) in GRUB and boot with all three monitors connected, the DM (lightdm/sddm) would just freeze after a few seconds. Keyboard and mouse stop working too, so I cannot get into another tty. However, if only one external monitor is connected it boots fine.

Strangly, GDM itself does not freeze when all monitors are connected, but then awesomeWM freezes right after I login.

Journalctl-Logs: https://drive.google.com/file/d/1OR-CeO … sp=sharing

EDIT:
I can see an error showing nvidia-gpu 0000:01:00.3: i2c timeout error e0000000
Based on my research, people say this error is thrown for NVIDIA-cards that have no USB-C port, but, my card has a USB-C port and the 2 external monitors are connected to it (with a hub)

Can anyone point me in the right direction, what might be causing this issue? tried posting on the NVIDIA support forum, but to no avail.

Hello, I got something similar on my laptop with Nvidia GPU
Have you tried to check the log with "sudo journalctl" ? When you are done, have you error in it and what is it ?

sorry for my English it's not my native language

Re: NVIDIA KMS freezes system with multimonitor setup

in log you have

Apr 13 10:13:08 archlegion kernel: nvidia-gpu 0000:01:00.3: i2c timeout error e0000000

create a file "/etc/modprobe.d/blacklist_i2c-nvidia-gpu.conf" with content "blacklist i2c_nvidia_gpu"
i hope this will help you

Unfortunately, this did not solve the issue. Still getting the page fault error at the end.
