[Bug 251278] Re: Notebook Ambient Light Sensor Disfunction

 

Just updating this bug, since I'm running into it on my UX302LG. It
looks like it should be fixed in future kernel releases, so it'd be
useful to know if the patches mentioned here are actually in the next
Ubuntu release (14.10):

In the mean time, the alternate driver from github seems to work:

Controller

       Status: Expired => Confirmed

Title:
  Notebook Ambient Light Sensor Disfunction

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  When attempting to run Ubuntu or it's variants on an Asus notebook
  which has an ambient light sensor, the sensor does not work correctly
  and the screen remains too dim to be productive or truly usable. My
  particular Asus notebook that is affected by this bug is a model
  M50Sv.

  There are various proposed fixes published on the net, but they all
  either do not work as described, or they are only temporary and do not
  carry over ofter re-booting.

  This bug essentially makes using Ubuntu and it's variants utterly
  impractical and unproductive. The eye strain caused by this bug is
  unbearable.

  This bug is accruing on other makes and models of notebooks which
  incorporate an ambient light sensor as well.
