Hi,

I understand that could be answered in other topic but I tried all other topic didn’t resolve my problem.

I do want to run my system on the NVIDIA card and use my Radeon card on a VM.

My system seems to boot on Radeon card, switch it in VFIO as I need for my VM so all boot display disappear but not switch to the NVIDIA card.

similar issue, my ubuntu get stuck on the boot splash screen … I had to remove the driver and switch to the open-source noveau, to be able to boot and use my system - still looking for a solution, as I need the nvidia driver!

I know it is very well documented on the web, but in case is needed - this is the procedure I use to temporary switch to the OS driver:

  • at boot press ‘esc’ to access the grub interface (press it only once, otherwise you go in the grub shell)
  • select other options, and reboot in rescue mode
  • select ‘enable networking’
  • select ‘root session’
  • from the root shell in rescue mode run apt-get --purge remove *nvidia* # note: this will remove also packages like docker-nvidia

… the system should now boot, now pray for a driver kernel upgrade that will fix the issue … hopefully, will happen soon

Is there a better solution than removing nvidia drivers?

I don’t know if this is the case for everyone, but following this discussion: Black screen after install of nvidia driver ubuntu - #175 by remo.fischer

I tried to unplug one of my two DP monitors and I was able to boot with the kernel running the NVIDIA drivers

I still need to test with an HDMI cable … hope that helps as a temporary workaround.

EDIT:
It does work with HDMI

Finally received a Radeon card and it works with both card!

I think that the other card wasn’t compatible with my MSI TRX40 motherboard cause I removed the second card (GPU) and had 02 error that means that no display card working!

Thanks anyway!
