What is the best way to turn off the Ubuntu beep permanently?
My Kubuntu installation makes me jump every now and then by emitting a hideous beep - generally when I reach the limit of a text field etc. How can I turn it off? I have tried the following:
sudo modprobe -r pcspkr
sudo rmmod pcspkr
And I have added the following into /etc/modprobe.d/blacklist:
blacklist pcspkr
But the beep persists...
