Title:
  HP ProBook 4540s brightness control problems

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I bought a laptop in December 2012, immediately tried to put Ubuntu
  12.10, got broken wi-fi and non-working graphics acceleration. Updated
  kernel to version 3.6, with graphic acceleration was all right, even
  partially earned wi-fi. After some time wi-fi hang, helped only
  restart the network subsystem.

  Updated kernel to 3.7, with the wi-fi was all became normal, but
  stopped working brightness control with the Fn keys. Progress bar
  indicates that the brightness changes, but in fact nothing happens.

  Tried the new distribution 13.04, on 3.8 kernels, 3.9, 3.10, nothing
  changes. Upon adjustment has broken in 3.7 kernel. It turns out that
  this is a regression.

  Hardware Configuration:
  Intel Core I5 3210M
  Intel HD 4000
  8 gigs of ram
  Ralink corp. RT3290
  Ubuntu 13.04 x64
