This laptop is HP Pavilion dv7-4272us.

I'd be willing to help debug this problem, but I need some tools.

The first tool I need is a way to reliably turn off the DIS graphics &
keep it off.

The second tool would be a way to reliably turn off the IGD graphics &
keep it off.

Etc.

When things keep switching back & forth for no apparent reason, I can't
debug the situation.

I did some Google searching, and it appears that there may be a way to disable
certain PCI addresses during boot, which may be the only way to control this behavior.

Thx for any help.

Title:
  Xorg radeon.dpm=1 causes glitches

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  Setting radeon.dpm=1 keeps causing glitches every time the display
  changes from the IGD to DIS and vice versa.

  It may be related to the HDMI audio, which I tried to turn off using
  radeon.audio=0.

  Below are the lines from the kernel log having to do with
  snd_hda_intel (which shouldn't be there when radeon.audio=0).  I'm
  trying to _keep the DIS GPU *turned off* in order to save power & keep
  this laptop cool_.

  I can't tell who keeps turning the DIS GPU back on, but I'd love to
  know how to keep the DIS GPU locked OFF.
