This is my most needed feature in linux. I want zero ‘connect/disconnect’ sounds and if the laptop is asleep I don’t want it to wake up in the middle of the night for no reason.
I have an infinite supply of Windows laptops from work but I hate them with a burning passion and I can’t afford to replace my Macbook.
If someone can tell me what linux distro is the most silent and least annoying I will erase my entire Windows partition this weekend.
A new Linux OS may emit unfamiliar sounds if some network app is still running and set to use them for notifications. Quitting the (sound-making) app(s) and/or the network connection will can avoid that problem. Of course you can just turn the sound volume all the way down.
Suspended OSs may sometimes ‘wake up for no reason’ if some vibration causes the mouse, for example, to jiggle around enough.
Logging out of your user account before suspending/sleeping the machine will stop that stuff without having to dig thru settings. Faster to log back in than to reboot.
