[Bug 1460419] Re: Display does not work fot the decrease screen brightness

 

Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a "regular" (non-security) bug.  I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross privilege boundaries nor directly cause loss of data/privacy.
Please feel free to report any other bugs you may find.

  only has a problem I just over 2 or 3 months I started using Ubuntu
  was one of the versions or Linux distros more just like it has a
  little problem in my I can not decrease the screen brightness type I
  press the shortcut s keyboard to decrease or will in their own
  settings and tail off so that decreases does not continue the same
  brightness would like the group of developers solve this problem and
  send as soon as possible an update that resolves this problem I use
  the Ubuntu version 14.04.2 for one of the best in my opinion and I
  have achieved many new users a few more that have notebooks with the
  same processor that mine or similar to c-70 amd have the same problem
  if you can send an update to all who use these processors I spoke as
  soon as possible would be of great help and I helped reporting this
  issue to the next version of Ubuntu this problem appears not as I like
  the version 14.04.2 I I would like them to send an update for my
  version solving this problem not only for min as to everyone with the
  same problem Thank you living free software Ubuntu one of the best
