This is probably a PowerDevil question.
This warning appears intermittently in my "Battery and Brightness" system tray popup:
"/opt/HipChat4/bin/HipVhat4 is currently suppressing power management: Uploading data"

And as stated, this laptop does not dim screen or goes to sleep as long as the HipChat4 application is running. If it the app stops running, everything works as expected and the warning goes away.

My questions are:
- is there any logfile where I could find information to debug this issue?
- is there any workaround that would allow PowerDevil to ignore whatever HipChat4 is doing and turn on power management features as normal?
- what is this application possibly doing wrong and what could they do to fix it?

Versions:
- Kubuntu 15.10
- plasma-desktop 4:5.5.4-0ubuntu1~ubuntu15.10~ppa1
- powerdevil 4:5.5.4-0ubuntu1~ubuntu15.10~ppa1

The HipChat4 application can be found here: https://www.hipchat.com/downloads.

you could try

Code: Select all

journalctl |grep powerdevil

and

Code: Select all

journalctl | grep hipchat4

but if Hipchat4 is "Uploading data" isn't this the correct action?

Sadly, there is nothing relevant in journalctl output.

Yes, powerdevil is probably doing the right thing if hipchat4 is actually uploading data. The problem is that this app seems to be doing it once every minute or so (that's about the frequency the warning appears in the system tray) even though there is no activity visible in the app. That prevents power management from ever kicking in.

I got an answer from Kai Uwe, a PowerDevil developer:

"If an application misbehaves, there's not a lot we can do. If you can update to Plasma 5.6, I made PowerDevil wait 5s before actually enforcing an inhibition as I had my screen wake up whenever I received a notification which had Chrome briefly block power management. I suppose this should already remedy your situation.

Also, I've been planning for a while to add some config options for inhibitions so you could temporarily and/or permanently prevent a specific app from blocking PM; I just haven't had the time (and motivation to implement this yet. "

Atlassian opened a Hipchat ticket about this: https://jira.atlassian.com/browse/HCPUB-574.
