IBM Ideapad Y580

Hardware Overview

Since the mouse doesn't register as a synaptic mouse light tapping gets registered as a click making typing difficult
Sleep key and wireless on/off key do nothing
The "Enable/Disable" screen key works as expected
Suspend/resume functions even from within X (with VT)
The brightness keys on up and down change the ACPI brightness value. However there is no impact on the screen itself
/dev/speaker just does not function at all
the boot method must be set to "legacy" in BIOS in order to boot
intel_backlight from intel-gpu-tools works to change the backlight
