Same here w/ a D810 within GNOME, standby, sound, power key work out of
the box (LID light does too, but directly from the BIOS apparently -
the GNOME applet doesn't do its job here BTW). I think that I've had to
add a `setkeycodes e00a 205` in rc.local to get the fn+hibernate key
working. Nothing done to the acpi events config (but LID closing
detection).
