Until today I was running Ubuntu 15.04, and finally got to the point
where I could run my HP computer with the Radeon discrete graphics
disabled/*turned off* -- even when watching video with the VLC video
player.

However, after upgrading to Ubuntu 15.10 today, the Radeon discrete
graphics keeps coming on, even though I'm trying to force it to stay in
the "PX asic powered off" state.

There are several problems with the Radeon discrete graphics:
* when it comes on & goes off it glitches the display and the Bluetooth mouse and glitches the audio
* it cause this laptop to run 10 degrees F hotter.

How can I disable the discrete Radeon graphics unit so that it *stays
powered off* ?

I have already registered several bugs wrt to this problem:
* Bug 1466934
* Bug 1467274
* Bug 1466950

Bottom line: I want to *keep the Radeon discrete graphics unit turned
off*, and do not wish to use this unit for any "hardware decoding",
"hardware rendering", or *anything*.

My AMD 3-core CPU is powerful enough to do *software rendering* for
anything I want to do, so I don't really need or want the discrete
Radeon graphics running on this computer.  (I have other computers
available should I need HW encoding/decoding/rendering assist.)
