You probably guessed by the title I'm a noob. Anyone had experience with this?

I did look at a guide for this using virt-manager, When I find it I will post it.

There are a few guides on the net for it like here

It does have an LTS kernel, IIRC it will give you the option upon install but not entirely sure on that. If not its a single click install from within the Manjaro manager.

thanks again, any idea how i can change the default GPU in linux, it's currently only displaying via the nvidia card in pci slot 1 and not the rx 580 in slot 2

Easiest is to swap slots tbh.

You can set it via zorg,conf. Trying to find a example for mixed GPU configs

Edit:

Create a file named "20-amdgpu.conf"

Add

Code:

Section "Device"
    Identifier "AMD"
    Driver "amdgpu"
    Option "DRI" "3"
    Option "TearFree" "true"
EndSection

Place in "/etc/X11/xorg.conf.d"
