@Fernando: we don't support hybrid graphics without using a display
manager, as that would prevent gpu-manager from running at the right
time.

@Michael: I can only assume there was some failure somewhere when
setting the power state of the NVIDIA GPU (the dmesg output might help).
There are indeed cases in which bbswitch works best on some GPUs. This
sounds like one of them.

@Stefan: good. Thanks for reporting :)

@Krzysztof: in your case, the NVIDIA GPU seems to be first, and the
Intel GPU is seen as last. Can you set Intel as first in the BIOS,
please?
