Bug ID: 434956
Summary: Add ability to ignore wake lock (Presentation mode
that suppressing Screen Energy Saving and disable ACPI
Sleep) from specific apps
Product: Powerdevil
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: mur...@gmail.com
Target Milestone: ---
Chromium-based web browsers and apps (for example, MellowPlayer) turns on the
"Wake Lock" mode, that enables the Presentation Mode in KDE Plasma environment,
which disables not only the system Suspend (ACPI Sleep States), but blocks the
Screen Energy Saving mode too.
This is good when you watch the video, but bad when you listen the music only,
or listen only audio track from video in background.
For example, when I playing Spotify in MellowPlayer app, that is minimized to
tray, in "Battery and Brightness" plasmoid I see all time the permanent
message:
```
/usr/bin/MellowPlayer is currently suppressing power management: Playing Audio
```
and sometimes even:
```
/usr/bin/MellowPlayer is currently suppressing power management: Video Wake
Lock
```
The main problem, that chromium/blink browser engine turns on the "Wake Lock"
not only when showing Video, but when playing audio - too! So when my computer
plays the music long time, my Display is always on and burns out :(
Maybe this happens because KDE (and maybe other DE too?) have only one "Wake
lock" mode, that disables both (ACPI Sleep and Screen Energy Saving, and no
ways to disable only ACPI Deep Sleep?
The good workaround for this problem can be adding to KDE Plasma ability to
manually mark specific apps from setting the global system Wake Lock. Can you
please add this feature, as workaround for described problem?
It can be located in "System Settings / Energy Saving / Advanced Settings"
page, where to show list of current apps, that have set the Wake Lock, with
"Ignore this app" checkbox, and ability to manually add custom app to this
list.
