System freezes when using prime

Hi @SendHelp. and welcome!

That, indeed, sounds peculiar.

Please provide the output for:

sudo mhwd --list

as well as

sudo mhwd --listavailable

And

sudo lspci

*PHEW*

I think that’s it!

Edit:

Nope. It wasn’t. Also see [HowTo] Provide System Information and [HowTo] post screenshots and links if and where applicable.
