Re: [Bug 1467274] Re: Xorg radeon.dpm=1 causes glitches
Re: "if you remove kernel parameters radeon.dpm=1
radeon.audio=0 are there any visual glitches?"
I believe so, but I'll check this again & send you another email.
As I mentioned in several bug reports, my goal is to minimize
the operating temperature of this laptop, which tends to run
hot even in Windows 7.
The good news is that Ubuntu 15.05 runs less hot than Win7 under
exactly the same workload -- playing the same videos with VLC.
Interestingly, the DIS GPU takes a lot more power to display
hidef H264 video than does the CPU, so the lowest power way to
play videos is to keep the DIS GPU completely turned off, and
to clamp the operating freq of the triple cores to 800MHz. Thanks
to clever programming for h264 decode, there is still enough
computing power of 3 cores at 800MHz to display the video.
For 1080p, I have to unclamp the cpu frequencies ("ondemand" v
"low"), but this raises the operating temperature by only a
handful of degrees C.

Title:
[HP Pavilion dv7-4272us] 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.
