Well, could you please explain yourself a bit more?

This *is* a bug. It is bad for UX. Maybe not in Xorg, but it is a bug.

As stated in the LKML, the behavior among drivers varies. Some backends *do*
turn off backlight completely. That means, there is something visible on screen
if you shine a bright light on the LCD (so the LCD is still working), but
because the backlight is off the screen is practically unusable (even in a very
dark room). This means your statement:

> 0 brightness == min brightness, not off

Is not always true. Not on my system, and not on the system of many other
people.

With that out of the way, could you please tell me where I should go to get
this bug fixed, if it's not Xorg?
