Yes and it is expected and somthing Jesse knows. However, if I started with
level 5 (using acpi video driver, i.e., native ACPI methods), the X server
first sets level to 0 (using DPMS off in init or preinit) and then using xrandr
init (later in init), it has still level 0 and kicks it to 15..

this is what I'm speaking about.

As you can see, get and set property in randr code related to lvds reads and
sets backlight levels unconditionally. Which could be OK unless you set DPMS
OFF before.
