It also seems strange for the brightness slider to go all the way down to zero brightness. Do any other desktop environments or operating systems do that?
  
  
  On macOS, it turns the backlight off but keeps the screen on. But yeah, I can see how this isn't exactly very useful. I think I'm okay with the bottom level turning off the screen entirely.

Nate's situation would be similar to before the patch was applied: only the lowest brightness setting turns off his screen. So there wouldn't be a regression for Nate.

  Well it's not me that matters; it's all the other people with weird screens like mine, as well as the prople whose screens don't do this. We need to wither come up with a solution that works for everyone, or else mark some class of screen as misconfigured so we can tell those people to file kernel bugs.
