Screen Blanking does not work when Chromium is running

Reported by appropri...@gmail.com, Jan 29 2017

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/55.0.2883.87 Chrome/55.0.2883.87 Safari/537.36

Steps to reproduce the problem:
1. Leave chromium running
2. 
3. 

What is the expected behavior?
Xfce power manager should blank the screen after set timeout.

What went wrong?
Screen did not blank

Did this work before? Yes Not sure

Chrome version: 55.0.2883.87  Channel: stable
OS Version: Ubuntu 16.04.1 LTS
Flash Version: flashplugin_20170110.1-0ubuntu0.16.04.1_amd64

I have posted information at two places:

https://productforums.google.com/forum/#!topic/chrome/EZpNDL4GzyU;context-place=forum/chrome

https://forum.xfce.org/viewtopic.php?pid=44252#p44252

The second one is where we discovered the issue is with Chromium.
 
It is mentioned in the links, but I guess it would help if I stated that this started last week, presumably after an update, which I do most weekdays.
Oh, and here is what tells us it was Chromium.

TRACE[xfpm-inhibit.c:343] xfpm_inhibit_inhibit(): Inhibit send application name=/usr/lib/chromium-browser/chromium-browser reason=WebRTC has active PeerConnections sender=:1.98
TRACE[xfpm-inhibit.c:101] xfpm_inhibit_has_inhibit_changed(): Inhibit added

The rest of the Xfce power manager debug info is at that second link.

Assigning this issue to MTV team as chrome-Hyd team do not have this OS(Ubuntu 16.04.1 LTS) to triage.
Adding "TE-NeedsTriageFromMTV" for further triaging.
Thank you!!
Seeing the same in beta Version 57.0.2987.37 beta (64-bit) on Linux

Good Morning,

I am not sure what happened, but as of this morning, this no longer appears to be a problem. Here is a list of what was upgraded yesterday:

ffmpeg libavcodec-dev libavcodec-extra libavcodec-ffmpeg-extra56
  libavdevice-dev libavdevice-ffmpeg56 libavfilter-dev libavfilter-ffmpeg5
  libavformat-dev libavformat-ffmpeg56 libavresample-dev libavresample-ffmpeg2
  libavutil-dev libavutil-ffmpeg54 libpostproc-dev libpostproc-ffmpeg53
  libswresample-dev libswresample-ffmpeg1 libswscale-dev libswscale-ffmpeg3

While I don't see Chromium in that list, maybe one of those caused an issue.

Thanks for your time and attention.

Do be so quick. I've had this problem come and go a lot over the months, so it might come back quickly.

It might also be based on what you're browsing. Sometimes I got the impression that a website that played video might disable the blanking  but then forget to re-enable later.

I could never track it down
OK. I did watch a You Tube video this morning. Not something I do with any regularity. I have re-booted into Windows to run my Flight Simulator, but will go back to Linux shortly. I will keep an eye on it.
Your right. Logged back into Linux opened Chromium and tested. No blanking. I then went and watched that same video, and then tested again. No blanking. Sigh!
Chromium updated this morning, along with the kernel, and this issue appears to have been fixed. I tested both before a reboot, after a reboot, and after another reboot. I will keep an eye on it and let you know if it reverts again. Thanks for the efforts.
Agreed, it seems fixed on beta as of sometime last week

Version 57.0.2987.74 beta (64-bit)

Arch Linux updated to 57.0.2987.98 (64-bit) and this issue seems to be fixed.
