@BeanMan I moved your post, because it is the same topic and you didn’t choose a solution.
Please provide some basic information about your system:
inxi -Fazy
mhwd -l && mhwd -li
It depends on the driver, if you can use bumblebee or prime.
PRIME - ArchWiki
Bumblebee - ArchWiki
Bumblebee doesn’t work out of the box and need some manual configuration.
