I got annoyed with the system beep of Linux Mint Debian Edition when I login or logout. I have found some solutions like:
echo "blacklist pcspkr" | sudo tee -a /etc/modprobe.d/blacklist
but it didn't work for me. How can I turn off the beep?
lsmod | grep pcspkr
Well, the easiest is to set setterm -blength, It'll set the beep length to 0.
when it's about X, then I'd advice xset b off, it'll disable the beep in X.
xset b off
