Can't even install Ubuntu 20.04

[Momo50]

Hi folks!

 

I just got a new Radeon RX 6700XT (lucky one). Turns out, when attempting to install 20.04 from scratch, the common install menu does not even load: after DVD install media check for errors, screen goes black.

 

I've noticed that even the "media check for errors" screen is different than usual (had installed 20.04 previously on this PC with old GPU), like super basic text graphics.

 

What might be the problem? Can it be that 20.04 installer does not have basic drivers for the 6700XT so it does not even display the install menu?

 

Thanks a million!

I'm a big noob in Linux but I have some little experience with Pop_OS! which is based on Ubuntu and you can choose NVIDIA or AMD installer and it comes with almost the newest drivers. I would give that one a try if you explicitly don't need just Ubuntu. I haven't had any issues with installing it so far on different systems.

It's on system76 website.

The 6700XT is probably to new for Ubuntu 20.04. Manjaro or Fedora 34 Beta would probably have better out of the box support.

It will need to be on kernel 5.10+ with the upstream linux-firmware and possible a more recent version of Mesa than what Ubuntu offers.

So, I guess from your words that this is expected behavior of the installer due to lack of recent drivers on Ubuntu 20.04 DVD installer. Just wondered if this "black screen issue" was due to lack of drivers for the super recent RX6700XT or perhaps the problem came from elsewhere.... Although as said, Ubuntu 20.04 DVD installer worked just fine on the same PC with previous GPU.

 

Thanks!

Thanks for the suggestion, I'll keep it in mind ^^ Cheers!!

Yes it would be expected behavior. You could try booting in safe graphics mode or adding "nomodeset" to grub boot to see if you can install it, but afterwards you would need to upgrade the packages i mentioned to a more upstream version for the system to actually be usable.

Thanks again. I'll look for the options you and WereCat suggest. Cheers!

You could start off troubleshooting by pulling the GPU from the system and connecting the monitor to the outlet of the MoBo. 

Is your PSU strong enough?

Also if* CPU has onboard video. Another option would be trying a distro with regular updates as opposed to LTS. Or hit the distro forums. May have an answer there.

Like this one from TSF

The point here still holds.  When it comes to graphics drivers,  PCLOS is ahead of the 'buntus.  Especially with nVidia drivers.
