Power Management (PM)

The discrete graphics card can be disabled by using ACPI methods. We're using either bbswitch (a module developed by Lekensteyn) or vga_switcheroo (compiled into the kernel) to do this in Bumblebee.

Since Bumblebee 3.0, this feature is enabled by default, using bbswitch. This allows for automatic PM, without any additional configuration. It's not the perfect solution and may not work on some laptops.

If Power Management doesn't work (please check the FAQ to be sure of this first) on your model using bbswitch, follow the Reporting bugs instructions on https://github.com/Bumblebee-Project/bbswitch. On Ubuntu, the installation of the mentioned tools can be done with:

sudo apt-get install acpidump iasl dmidecode

If on Fedora:

sudo yum install pmtools iasl

If on ArchLinux:

# pacman -S pmtools iasl dmidecode

If you do not want to use Launchpad, send the report to lekensteyn@gmail.com. In the subject put the name of the .tar.gz file and add the output of the next command to the mail itself:

lspci -vnn | grep '\''[030[02]\]'

Please mention the marketing reference of your computer as well (name under which you bought it).
