SUMMARY When a laptop gets unplugged from power while in stand by, when resuming from stand by the unplugged sound gets played. This is misleading as the two events can be hours or minutes apart. Also it's very disturbing, as a laptop may be brought back from stand-by during a class or meeting. The volume might be set to loud, which makes this a bad experience. STEPS TO REPRODUCE 1. Plug laptop to power 2. Put laptop in sleep/stand-by mode 3. Unplug laptop from power 4. Resume from sleep/stand-by mode OBSERVED RESULT Unplugged from power notification sound is played. EXPECTED RESULT Unplugged from power notification sound not to be played. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora 29 KDE (available in About System) KDE Plasma Version: 5.14.5 KDE Frameworks Version: 5.55.0 Qt Version: 5.11.3 ADDITIONAL INFORMATION Just to be clear, I'm referring only to the specific scenario of the sound being played when resuming from stand-by, not during general use.
lol this is currently being inhibited by https://bugzilla.kernel.org/show_bug.cgi?id=210425. Once that's fixed, this will return.
