[SOLVED] xrandr: Configure crtc 4 failed

I have been trying to set up up multihead on my arch install where the first screen is my laptop and the second one is a monitor connected using HDMI cable. As seen in the wiki, trying to do it using xrandr --auto gives an error

    xrandr: Configure crtc 4 failed

After a lot of googling and scouring the wiki and not finding any answers, I came here. I even tried setting it up using xorg.conf but doing that opens the tty in my laptop screen, and when I startx, it opens in the second screen. Leaving the tty open in the first screen. Any help would be appreciated and please tell me what I can provide to make it better for you to troubleshoot.

please post xorg log and the outputs of

$ lspci -k
$ xrandr
$ xrandr --listproviders

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
Did you use the guided installer ? If yes, I can't help you.

Hey so I have been tinkering with it and I figured out that this was happening because my HDMI output was connected to the dGPU. So now I have two options: Reverse PRIME offloading or making the NVIDIA my primary GPU. I made the NVIDIA gpu my primary and now I can configure the screens using xrandr. Marking this as solved.
