Well, what might also be a problem is Nvidia optimus (if the hardware supports it). You might have to entirely disable either the CPU integrated GPU or the dedicated GPU.The only things that may or may not work, are your network interface(s) (wired and/or wireless) and bluetooth. Everything else is pretty much standard and should work out of the box.
Working here on `X1 Carbon Gen9` with `i7-1185G7` onboard.Oh... and on my i7-1185 laptop (Lenovo Thinkpad X1 Carbon Gen9) the speakers are not working.
