Title:
  Trying to maximize battery life on HP dv7-4272us

Status in xorg package in Ubuntu:
  Invalid

Bug description:
  This AMD 3-core + Radeon runs really hot, and I'm trying to maximize
  battery life.

  When I try radeon.dpm=1, I get display glitching every few seconds
  when the dpm switches displays.  I haven't found any way to force dpm
  to keep the discrete display completely turned off, both to save power
  and to stop the glitching.

  Among other problems, the mere existence of HDMI audio keeps waking up
  the discrete GPU, both wasting power & glitching the display.  So I
  tried radeon.audio=0.  I don't think it helps, but I left it in.

  The only way to really kill the HDMI audio problems is to blacklist
  snd_hda_intel, but that kills _all_ of my audio (except Bluetooth
  audio).  So I had to un-blacklist snd_hda_intel.

  So I'm using radeon.dpm=0.

  If radeon.runpm=1, I still get problems.

  So I'm using radeon.runpm=0.

  This works pretty well; I've gotten the temperature down to 68 degrees
  or so, but this is still too hot.

  If I turn off the discrete graphics completely using

  echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

  this works quite well -- I can get the temperature down to 64 degrees
  or so -- but now my log fills up with complaints that my radeon
  discrete driver isn't turned on.  (I'll send you another report
  showing you this.)

  I want to be able to operate this HP laptop in the most power-saving
  way -- by completely turning off the discrete radeon GPU.

  Could you provide any suggestions about how to do this?

  Thanks very much.
