%description
bbswitch is a Linux kernel module which automatically detects the required 
ACPI calls for two kinds of Optimus laptops. It has been verified to work 
with "real" Optimus and "legacy" Optimus laptops.

See: https://github.com/Bumblebee-Project/bbswitch/

For further information.

For now, if you require nvidia module support with bumblebee you must 
install bbswitch. In addition, even with nouveau, bbswitch will work 
after a suspend whereas vga_switcharoo in the kernel might not. See:
https://github.com/Bumblebee-Project/Bumblebee/wiki/Comparison-of-PM-methods
for further information.
