Title:
Discrete Radeon graphics unit won't stay *off*
Status
Hi Christopher:
OK, I have some additional information.
1. I finally figured out a way to kill the Radeon HDMI audio:
echo 1 > /sys/bus/pci/devices/:02:00.1/remove
If I do this after I log into Ubuntu, the Radeon HDMI option is gone,
and won't return until I reboot.
The other audio
Will do, but not for a few more days. I'm working on something with a
deadline.
Thx for helping with this; there's no reason why radeon.dpm=0 and radeon.dpm=1
shouldn't *both* work, although somewhat differently.
