Booting and installing on Nvidia hybrid bumblebee laptop

There is a subset of laptops that will not boot without these intervening steps even with the live media, maybe they are all bumbleb ee..
If anyone has a list of effected systems it would be nice. I know in involves Nvidia chipped systems.


  1. Boot live media by passing kernel parameter systemd.mask=mhwd-live.service that should get you to live session
  2. Now before you start the install from the live session change the lines at the end of the file /lib/calamares/modules/mhwdcfg/ to match below
def run():
    """ Configure the hardware """
    mhwd = MhwdController()
    # return
    return None # <- Add this and comment the above line
  1. Now run the installer and it should work. Reboot your system and proceed.

Pay attention -- After the reboot you need to do the next steps, you may need to write it down.

  1. Add the following kernel flags at the Grub boot menu otherwise the system won’t boot:
    acpi_osi=! acpi_osi="Windows 2009"
  2. Test system after boot to see if it is working see the first command below
$ systemctl status bumblebeed
optirun -b none nvidia-settings -c :8

You should see the nvidia-settings showing your dedicated GPU.

Now make it Permenant: >>>>>> Do not skip this Last step

Don't forget to add acpi_osi=! acpi_osi=\"Windows 2009\" to your GRUB_CMDLINE_LINUX_DEFAULT in the file /etc/default/grub
And then at the terminal run
sudo update-grub

Look also, you will see other suggestions such as "Windows 2015" etc... I have not tested them but if someone else has verified it works then go with whatever works for your laptop.
