I have asus tuf fx705dt laptop. I has amd and nvidia video.
When I installed ubuntu, external monitor (hdmi) doesnt work.
I did this steps and it fixed:
But now, after some updates i think. When I unplugged my external monitor and move to some other place, when I open screen I saw:
nvidiea-modeset: ERROR: GPU:0: Idling display engine timed out: 0x000c57d:0:0:291
And if I reboot , laptop screen is in blank. To fix I need to turn on when display connected to hdmi and then unplug without locking screen/close laptop.
I attached debug when screen is in blank (but CTRL+ALT+Fx works)

Now I use Ubuntu 20.04 with plasma/kde and sddm.
Best Regards !
