#4893: Turning brightness all the way down turns some screens off
----------------------------+--------------------------
       Reporter:  SAMdroid  |       Owner:
           Type:  defect    |      Status:  new
       Priority:  Normal    |   Milestone:  Unspecified
      Component:  Sugar     |     Version:  Unspecified
       Severity:  Major     |    Keywords:
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
