Hi, I’m trying to install CachyOS on a Dell G15 laptop (Intel Comet Lake-H + GTX 1650 Ti).

What I’ve tried:
Created USB with Rufus (reflashed using DD mode)
Tried LTS kernel and legacy nomodeset option
Edited GRUB with:
nomodeset
i915.modeset=0/1
systemd.unit=multi-user.target
Tested external monitor (C2 LG OLED)

What happens:
GRUB loads fine
Boot starts
Screen goes black on both laptop and external display
System becomes unresponsive (Caps Lock does not respond)

Result:
The system appears to freeze during early boot.
Not sure if this is related to kernel, Intel/NVIDIA hybrid graphics, or firmware/UEFI.
Any ideas appreciated.
