Locked screen doesn't stay in energy saving mode

[Roderick Johnstone]

Hi

Fully updated F24 system running Plasma desktop. Dual screen setup.

Screen locks correctly after time set in Energy Saving / Suspend session 
After

Screen goes into energy saving (screen blanks) after time set in Energy 
Saving / Screen Energy Saving Switch off after

But then the screen immediately comes out of energy saving and sits for 
ever with the screen locker displayed.

Anyone else see this?

Any ideas how to fix would be appreciated.

Thanks.

I don't use lock screen.  But I do have the case where my monitors won't go in to blank.

When this happens I click on the "Status and Notifications" triangle in my systray and
then select "Battery and Brightness" and it tells me what application is preventing the
blank.  For me it is normally Chrome and it due to an open WebRTC connection.  Finding and
killing the open tab is one way to clear it.  But sometimes I have to close Chrome and
restart.

I've search, in vain, for a way to ignore open WebRTC as a reason for keeping the screens
active.  :-(

Hi

Thanks, but I'm not seeing any applications listed in "Battery and 
Brightness".

Also, I notice this behaviour (screen comes out of power save 
immediately) on all the systems I manage and I'm pretty sure that not 
everyone has a WebRTC conenction open.

This started happening a few weeks ago, so presumably it was some update 
that caused it.
