This is my first post here, although I have been following your Mastodon account for a while. I am not a gamer myself, but have two teenagers that are getting more and more into it.
For the older one (13 years old as we speak), I am building a PC to play SteamOs games (City builder already purchased but unable to save projects due to gc). I surfed for long hours, so that I created so far this build (plus case and power source already in place):
https://fr.pcpartpicker.com/list/qp4ZWb
Motherboard firmware updated to the latest available one.
The thing is: I selected the graphic card (RX 570) because it seemed AMD had dedicated Linux drivers and that would help me get through just fine. I wanted a minimum 4GB of DDR3 memory on it. So far the project has become a nightmare. I have played around for hours with the motherboard settings for which GC to use (the one embedded in the processor or the RX 570), installed various versions of the AMD drivers to no avail.
A couple of times I have not managed to go back with changes, lost all of the installed Ubuntu and had to start all the way from the start. As of today, I have unplugged the graphic card and am considering to change it if I find an alternative simple, fast and not too expensive.
I have been digging in this forum for some insights, but w/o luck so far.
In a nutshell, a couple of straightforward questions:
- Should I be able to combine and make work my selected hardware, specially the graphic card? Updating to Ubuntu 20.04 coming up.
- What replacement should I consider for the GC if the Rx 570 is not a viable option?
Thanks in advance.

What do you want exactly? Change between the integrated and discrete cards? That's easy, you only need to use DRI_PRIME.
Let's clear things first, start from the very beginning.

Thanks for your quick reply.
I just want to use the discrete card. If I install Ubuntu 18.04 and plug the RX570 no display at all. Even when I disable the integrated card from the BIOS. That is why I went with the AMDGPU-PRO trial.
I will install a fresh Ubuntu 20.04 and will post back. So far with black screens all along, I have no clue whatsoever of what goes wrong in the first place.
Really sorry that I did not make myself clear in the first place.

@damarrin: I can reach the BIOS w/o issue, I make it all the way to the grub screen and from then on, darkness is my only friend. If I try to switch to a terminal (Ctrl + F1 for instance) I see millions of errors which I tried to write down and search for solutions to no avail. This was about ten days ago and had no records about it. However, I will retry and post back with clear details of my status.
It feels so good to have quick and intense feedback despite my lack of clarity :-)

And you can also share the output of
DRI_PRIME=0 glxinfo | grep OpenGLJust to be sure.
If I remember right, you will have to install the mesa-utils package for glxinfo, but the Terminal will tell you everything.

The newer AMD cards require the blobs (firmware) installed on Debian to get any output from the device at all, so if you get no output as the OS tries to launch your DE it is likely you do not have those installed. So grab those during installation (or on first boot in a tty). On ubuntu, amdgpu seems to be the package that has them, but better read after that yourself. You won't need the proprietary drivers (the ones you download from vendor site) as any desktop installation should include the necessary free drivers. For steam make sure to enable foreign architecture support for i386.
