Ubuntu isn't using AMD or Nvidia drivers properly

Is it just impossible to use Ubuntu with my current setup for the time being until there is better support for switchable Nvidia/AMD apu graphics?

I would assume you can use this system with 1 GPU disabled. But for dual support you will probably need kernel support or a new version of bumblebee. Or if you have a lot of time on your hands create a manual configuration for both and then merge those like we used to do when we needed 3 or more displays connected.

Would you mind starting a topic on the Phoronix forum with as much detail you can find about this? That is the place where all the kernel experts hang out and I believe the best way to get this rolling (This answer shows you why I am suggesting this: https://askubuntu.com/a/1228323/15811 Also see the comment about using a mainline kernel).

@Joe S. I am really sorry for the inconvenience. I did not know ubuntu-20.04 had a move compared to previous versions ,and since I did all my checks on iso using grub's loopback on iso sitting on hdd....

Anyway ,your usb stick is very probably still good ;all you have to do is

At boot prompt with "Try ubuntu without installing blabla"

1 Type "e" to edit the line "Try ubuntu..."

2 Replace "maybe-ubiquity" with "boot=casper"

3 Type F10 to boot

Everything should work now

Hope you get thru

 cheers

I only tried with gtx1650 on my acer nitro5. Would you try this liveimage I made which uses a modified prime using Mathieu Gras' idea; it allows live switch between intel and nvidia dgpu back and forth without rebooting.

I tried running cuda-11.0 'samples: they are fully working (nbody,oceanfft,fluidgl,smokedparticles with nvidia rendering)
