Disable Linux alarms

Problem:

Every time a RedHat input is wrong or something, the computer is screaming.

This sound is not from the external audio output device of the system, but from the inside of the machine (it should be a voice Generator controlled by the BIOS ).

 

Execute the following code without executing all the statements.

Setterm-bleng 0
Setterm-blength 0
Xset B off

Set the preceding statement ~ /. Bashrc.

==============

The following is another method:

Temporary solution

Sudo rmmod pcspkr

For Debian/Ubuntu users, you only need to open your terminal and run the above command. For Linux users in centos/RedHat/RHEL/fedora, Log On As root and run rmmod pcspkr.

Permanent solution

For Debian/Ubuntu systems, run the following command as root:
Sudo echo "blacklist pcspkr">/etc/modprobe. d/blacklist

For centos/RedHat/RHEL/Fedora systems, run the following command as root:
Echo "alias pcspkr off">/etc/modprobe. conf

 

The beep sound under the virtual terminal of X can be closed through xset B off. This command can be placed in the startx configuration file $ home/. xinitrc.
