I've got a nice little Acer netbook (maybe twelve years old?) that I use mainly for car camping and when I want to use a computer at the library. The problem is that *sometimes* when I use the 'action button' icon from either the 'main menu' or the 'panel' to suspend, shutdown, etc.; or, if I have to plugin or unplug the external charger/power supply for whatever reason, it emits an ear-splitting beep that makes anyone nearby jump right out of their skin and develop an instant case of PTSD. Does anyone know how I can disable this? _,met$$$$$gg. toma@11debXfceAO722 ,g$$$$$$$$$$$$$$$P. ------------------- ,g$$P" """Y$$.". OS: Debian GNU/Linux 11 (bullseye) x86_64 ,$$P' `$$$.
