Switch two GPU PCIe position

Mon Feb 03, 2020 2:27 pm
So far using KDE Neon with an AMD GPU on the first PCIe and an Nvidia on the second. I have a dual boot Win10/Neon system.
Now due to changing load type (from CUDA to 3D graphics) I need the Nvidia on the first PCIe, AMD will be in the second.
Trying the change Neon latest .5 release didn't boot, with a black screen where normally I find the GRUB menu for the OS choice.
Being not an expert want to ask if uninstalling proprietary Nvidia drivers so to start a "neutral" state will enable me to boot normally, or there are other problems.

Can you boot to BIOS Setup? A decent BIOS will detect which GPU is hooked to your monitor.
If you cant see the BIOS Setup screen nothing can be done except maybe a BIOS update.

I've seen the BIOS, but the problem come after choosing Neon as boot target in GRUB

But, just to be clear, you see stuff on screen at every boot when NVidia is in the first pcie slot - is that correct?
Please describe (be specific) what happens when you boot. do you see the grub menu at all? does it skip grub and boot to an OS? (any os)
