[foobar <hbaker1@xxxxxxxxxxxx>]

The video glitches only happen when the GPU switches between the GPU on
and the GPU off.

Otherwise, the display is solid, both when the GPU is enabled, and when
it is disabled.

Other symptoms:

The GPU turns on and off every 3 seconds or so when the system first
starts up.

However, after the CPU's reach a certain temperature -- ~60 Celsius --
the GPU then seems to stay off (more-or-less).

But if I start up VLC, VLC seems to try to turn the GPU on, and the
whole cycle starts again.  I have tried to disable "hardware decoding"
in VLC, but apparently that is harder than it looks.

I tried removing all of the VDPAU libraries, in hopes that VLC wouldn't
be able to fiddle with the GPU.

However, that didn't help.  (It didn't hurt, either.)

Something in the DRI module seems to want to keep the GPU turned on, and
I want to keep it turned off.

Please, please, tell me how to disable the GPU completely!

Thanks.

Title:
  [HP Pavilion dv7-4272us] Display glitches occur

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  Display glitches occur every time the display changes from the IGD to
  DIS, and vice versa.

  I'm trying to _keep the DIS GPU *turned off* in order to save power
  and 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.
