HP tm2 + windows 10 black screen workaround

[tmtwouser]

So there are plenty of old and locked posts about that integrated Intel/discrete AMD switchable graphics laptop not working with windows 10 because it results in a black screen. The reason is a mixup when windows 10 tries to drive both of its GPUs at once.

After some time trying to fix it, I found several ways:

1. You can trigger the recovery menu by interrupting its boot with the power button three times, and then navigate your way to booting in safe mode. There you can open device manager with a rightclick on the start menu and disable the AMD GPU. On the next boot everything will work fine.

2. You can blindly press these keys: Windows+P, fn+right arrow, enter; this switches windows 10's multi monitor mode to only use the "secondary" monitor, i.e. the one that you actually see when both GPUs are enabled.
