Description John Andrew McInnes 2025-11-20 21:18:27 UTC

SUMMARY
When you wake your displays (by moving the mouse, pressing the keyboard, etc.) It is detected as a hardware connected event and the System Notification for "Device Plugged In" is triggered. A sound plays. This is an annoyance. I like to hear the sound when I plug in a USB device. But I don't want to hear it every time I wake up my computer. It would be nice if there was a separate notification for displays. Or maybe none at all, since technically you aren't unplugging your display from the computer - the display just went to sleep.

STEPS TO REPRODUCE
1. login
2. wait for displays to go to sleep/get powered off
3. move mouse

OBSERVED RESULT
The "device plugged in" sound plays. In fact maybe even the "device unplugged" sound immediately followed by the "device plugged in" sound.

EXPECTED RESULT
In my opinion it would be nice if the notification didn't trigger for monitor wake up.

Thanks for the feature request and for the digging you did into the udev events. The developers can weigh in on how much effort it would be to separate out monitor attach events for this.
