[Bug 1467274] Re: Xorg radeon.dpm=1 causes glitches
foobar, just to confirm, if you remove kernel parameters radeon.dpm=1 radeon.audio=0 are there any visual glitches? ** Tags removed: needs-full-computer-model ** Tags added: latest-bios-f.29 ** Summary changed: - Xorg radeon.dpm=1 causes glitches + [HP Pavilion dv7-4272us] Xorg radeon.dpm=1 causes glitches -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1467274 Title: [HP Pavilion dv7-4272us] Xorg radeon.dpm=1 causes glitches To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1467274/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 1467274] Re: Xorg radeon.dpm=1 causes glitches
OK, Christopher, below are the results after removing radeon.dpm=1 and radeon.audio=0. Each time this happens, the screen glitches. It seems to be triggered by something in the audio. HDMI audio keeps showing up in the list of audio devices, even when radeon.audio was 0. I also started my Bluetooth A2DP headset, which may have triggered (why, I can't imagine) the switching on off of the HDMI audio. BTW, the temperature power consumption _without_ radeon.dpm=1 is almost exactly the same as _with_ radeon.dpm=1. Has dpm=1 become the default?

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. At 07:28 AM 7/4/2015, Christopher M.

Re: [Bug 1467274] Re: Xorg radeon.dpm=1 causes glitches
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.
