Laptop dGPU not recognized, monitor doesn't work anymore.

I have an "ASUS TUF Gaming A17 FA707NU_FA707NU 1.0" laptop, with an Nvidia 4050, however since this morning when i powered up my pc, the drivers just stopped working.
The display of my laptop works fine, but my monitor doesn't get recognized anymore.

lspci | grep VGA

35:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Rembrandt [Radeon 680M] (rev 0b)

lscpi only shows the internal AMD GPU.

nvidia-smi doesn't work at all:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I have the nvidia-dkms driver.
yay -Q | grep nvidia

I already tried to fix the problem by adding this "nvidia-drm.modeset=1 ibt=off" to my /etc/default/grub config (Of course i regenerated the /boot/grub/grub.cfg file afterwards), but to no avail:

GRUB_DEFAULT=saved
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet nvidia-drm.modeset=1 ibt=off"

Re: Laptop dGPU not recognized, monitor doesn't work anymore.

ALRIGHT I FIXED IT AFTER 4 HOURS!!!!

I actually had to install Windows for Armory Crate, and there i changed the power profile, and when i went back into linux it worked again!!!
