Installing Manjaro on my ASUS TUF GAMING FX504 SERIES

So first problem i run into is booting from the live image. But after googling a lot i could figure out something and now i am booting like following:

drivers=nonfree

and adding

systemd.mask=mhwd-live.service

to the boot options. After doing this i can boot into the live image. But than if i try to install it it would stuck. So edit the /usr/lib/calamares/modules/mhwdcfg/main.py From:

def run(self):
    for b in self.bus:
        for id in self.identifier['net']:
                self.configure(b, id)
        for id in self.identifier['video']:
                self.configure(b, id)

    return None

To:

def run(self):
    return None

After doing this i am able to install it with follwoing paritions drive 1: ssd /dev/nvme0n1p3 at /boot/efi with fat32 and 250mb /dev/nvme0n1p1 at /swap with linuxswap and 8GiB /dev/nvme0n1p2 at / with ext4 and 111GiB drive 2: hdd /dev/sda1 at /home with ntfs and 931.5GiB i had some errors with ext4... So now it is installed. After the first startup i am doing update:

sudo pacman -Syyu

after this is done i am rebooting and sometimes it stucks but starts after a hard power off. Next i tried to install bumblebee without luck and i had to retry... So i tried added this but i think it is not required in my newest installation i am not using it. /etc/default/grub:

acpi_osi=! acpi_osi='Windows 2009'

than i did:

sudo update-grub

and reboot than i will try so install my dual graphics nvida drivers

sudo mhwd -a pci nonfree 0300

But i am stuck at installing the nvidia bumblebee drivers... Everytime I install them no matter what i am stuck at a complete black screen after reboot and i cant enter with Alt+Ctrl+F1 ... With the free drivers it is running probably but with really bad performance. I tried one more thing which is discribed here: howto-set-up-prime-with-nvidia But after i did everything i am stuck at a black screen again but this time i can access different terminals via CTRL+Alt+F2 ...
