@d707ab89 I didn't manage to disable it entirely but I found a solution I am happy with. If you go to /sys/class/leds there are four folders for the different LED colors, in those folders are different files and one of them is called "repeat", if you simply set that in the blue folder to 1 instead of -1 the LED will only blink a single time!
@d707ab89 Nvm, it only stops the normal notifications, not the false triggers... :(
@d707ab89 That might actually not be the real issue, the configs seem to reset on reboot and possibly also in between, now I get why someone on Reddit suggested a script that constantly overwrites these configs but that doesn't sound like a great solution ether. I think I might write a EMail to Meggi for that one, they have a short blog post on the notification LED and usually know almost everything!
