[SOLVED]bbswitch/bumlebee stop working after update

I have reinstalled both, but still nothing.

sudo modprobe bbswitch

modprobe: ERROR: could not insert 'bbswitch': no such device

I have the bbswitch-dkms version installed from the AUR

If I try to run bumblebeed -vv i get:

ERROR: No discrete graphics card found

EDIT:

Okay, found the issue. Turns out having video.use_native_backlight=0 to solve my issue with the backlight not working under the new kernal, was stopping my discete graphics card from being detected.

To fix:
Under boot kernal params add "acpi_backlight=vendor" and then reinstall bbswitch-dkms and bumblebee and you should be away!
