Turning brightness all the way down turns some screens off

Reported by: SAMdroid Owned by:
Priority: Normal Milestone: Unspecified
Component: Sugar Version: Unspecified
Severity: Major Keywords:
Cc: Distribution/OS: Fedora
Bug Status: Unconfirmed


Steps to reproduce:

  1. Have laptop like mine (mine has an intel_backlight)
  2. Open frame
  3. Open display deviceicon
  4. Turn brightness all the way down
  5. Notice that the screen has turned 100% off. It's black. You can't see anything

Comment: GNOME stops me. When I go to 0% in GNOME it behaves normally.

It seems to be linked to /sys/class/backlight/intel_backlight/type = raw

Tested devices: Dell Inspiron 13 7000 2-in-1, Lenovo ThinkPad something

Version: 0.106

Thanks for the report, but I don't think this is a problem. It is easy to turn the brightness back one step. The entirely dark display does have a use-case; audio listening and power saving. The other indicators on most commodity machines show if the system is still active; power, wireless and disk LEDs.

My opinion is that GNOME has removed a useful feature, but I don't use GNOME. The Ubuntu Unity desktop does dim all the way to black.

I agree with you that is has a use case, however, I believe that this is not the correct ux.

It is confusing when your display turns off 100%. Users who are not as tech-savvy may believe it is a crash. Even users who are more tech savvy may not know where the brightness keyboard shortcuts are to turn the screen up more.

I believe it is better surfaced by a dedicated menu item rather than a confusing slider.

They'll learn quickly. We can't nanny them.
