[BUG] when there is an audio streaming clicght switches off the screen

[promeneur]

NOTE: Please try to upgrade Clight if not running on latest release, before reporting a bug!

Clight version the issue has been seen with:

clight 4.3 , clightd 5.2

Used distribution:

openSuse 15.2

Describe the bug clight does not takes care of audio streaming with for example the inbuilt explorer webkit in Akregator. After a delay monitor is switched off thus also the inbuilt speakers !

Expected behavior

clight does not switch off the screen when there is an audio streaming.

Hi,

I think this feels a little out of scope from Clight. It is hard to check such a setting- if you're using Pulse, should we inhibit when anything is playing? How should we tell when an output is internal speakers? etc.

You could use clight-gui or scripts manually to inhibit DPMS when you want, or with a more complicated solution use MPRIS to check if there is a "media player" running and inhibit. That is the point of the DBus interface, for automation. :) You can try disabling DPMS, and instead lowering your brightness to a really low number to keep the display on.

This is the same problem with the same feature of KDE in energy saving settings. I sent a bug report to KDE.

Hi! Indeed it seems like your music player does not send org.freedesktop.Screensaver.Inhibit request. That's why both clight and kde are having the same issue! Out of curiosity, which music player are you using?

[promeneur]

I use Firefox.

click on "écouter"

I experimented the same problem with qtwebkit in akregator.

[FedeDP]

It works fine here:

New ScreenSaver inhibition held by 'firefox': 'audio-playing'. Cookie: 1780419494.
ScreenSaver inhibition grabbed.
Inhibitions ctr: 1
Pausing DPMS
Emitting 'Inhibited' property
Pausing DIMMER

Can you share a verbose log? Firefox version?

I am guessing that either KDE or some dpms setting (eg: xset called by some script) is overpassing Clight (ie: it is not Clight switching off your screen, but something else).

I disabled kde "switch off screen".

Firefox version?

86.0

Care to share a verbose log?

[promeneur]

i have just experimented. This time no problem. The monitor is not switched off after 5 mn ! It's a random phenomenon.

clight.log

It seems like you are using

(D)[12:32:02]{interface.c:629} New ScreenSaver inhibition held by '/usr/bin/google-chrome-stable': 'Video Wake Lock'. Cookie: 603570492.

google chrome, not firefox ?

Maybe sometimes the browser does not send the Inhibit request?

[promeneur]

Strangely in log there is no occurrence of Firefox while listening an audio streaming.

The occurrences of Chrome are due to using permanently website as Instagram, Facebook, Twitter etc. with Chrome. Randomly the current item may content a video.

[promeneur]

I think that Firefox gets a problem.

Weird, i got firefox 86 and it works fine! @nullobsi care to test too? May be some misconfiguration, i don't really know. Does firefox inhibit screensaver when watching a video?

[promeneur]

Firefox+video viewing no problem.

That is weird; should work fine; Can you share output of busctl --user monitor org.freedesktop.ScreenSaver while starting/pausing audio play?

[promeneur]

today it works. Monitor is not switched off !

It seems a random phenomenon.
