MacBook Pro gpu switching, how to force using discreet gpu

Post by Jed » Fri Jan 19, 2018 7:42 pm

Hi!
I just installed Linux mint 18.3 cinnamon 64Bit on an older MacBook Pro 5,3 from 2009. Everything works so far, but it only uses the integrated gpu NVIDIA GeForce 9400m. Is there a way to use the discreet gpu NVIDIA GeForce 9600m GT for better performance?
I tried different approaches but all I found out were different ways to produce a black screen.
Both gpus are recognized but I can’t switch. It does not have to switch dynamically - manually or permanently would be ok.
