Thinkpad P50 | External LG Ultrawide works but native screen not.

Hi everyone!  I fell in love with Arch, no seriously I really did. So I look forward to spending many years in this community!

Everything is working perfectly now after a few days of tinkering.

The Real problem was getting my external screen to work with 3440x1440@60.

I always had only 1920x1080 or something.

Now I was wondering why it worked immediately (even with 3 monitors on the ubuntu life cd but I figured it was probably some special Ubuntu thing but it verified that everything SHOULD work.

Then I tried it with LinuxMint and discovered it worked there as well when I installed nvidia-39xx drivers.

Lo and behold it worked on arch as well (using xfce) when I just copied the generated xorg.conf from the LinuxMint install over to arch, added the "BusID" and installed the nvidia-39xx drivers as well.

[NOTE] I have set the BIOS to hybrid mode as this was the only way to make it work ( tested through dozens of reinstalls).
But I do not need prime or optimus or bumblebee since the Laptop is 99percent of the time on my desk.

But for some silly reason my arch just forgot the laptop screen itself..all that's there is a small white hyphen.

But when booting up the Laptop screen gets used. Also immediately when shutting down I can see the text running through.

xrandr doesn't have a second screen, neither does the display menu.

Below the most important output otherwise please ask and I will follow up within the hour.

I hope somebody out there has an idea :-)  This already took me the entire week but I really need to start some work again ;-)

The monitor is connected via HDMI.
