By default PRIME *should* be working ... are you certain the NV chip is powered and drawing power? Check /sys/kernel/debug/vgaswitcheroo/switch (just cat it) and see if the chip is already marked OFF (this requires nouveau to be loaded as a driver IIRC so remove your blacklist). https://www.kernel.org/doc/html/v4.10/gpu/vga-switcheroo.html If that already shows it off then you don't need to do anything else as Intel will be default. Alternatively if that's not behaving as expected for you follow the instructions for the bumblebee implementation: https://fedoraproject.org/wiki/Bumblebee _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
