Help Needed Asus ga502du popos

so my laptop is a Asus ga502du ryzen 3750h nvidia 1660ti max-q 120hz panel and i have installed popos-nvidia.iso when opening nvidia xsettings manger i get a tiny blank box so following instructions on the wifi instructions worked.
then added

nouveau.modeset=0 tpm_tis.interrupts=0 acpi_osi=Linux i915.preliminary_hw_support=1 idle=nomwait

to /etc/default/grub after the word spalsh

then had to make xorg.conf

Section “Module”
Load “modesetting”

Section “Device”
Identifier “nvidia”
Driver “nvidia”
BusID “1:0:0”
Option “AllowEmptyInitialConfiguration”
Option “ModeValidation” “NoDFPNativeResolutionCheck”
Option “ConnectedMonitor” “DFP-0”

put that in /etc/X11/

…ok so now nvidia xsettings actually displays something it shows i have a fake dfp-0 and a prime display recognized as my laptops display, the fake is being seen as the default which makes it a nearly impossible to sign in and the settings under gnome revert each time i reboot and nvidia xsettings says in can’t save x config file and opening nvidia with sudo doesn’t make a difference ether. that’s kinda a problem

oh and if someone also has an idea how to get the keyboard backlight to work i would really like to see my keyboard.

any help is greatly appreciated
