How to disable alarms and modify resolutions in linux (1)

LinuxClosingAlert soundAnd modifyResolutionThe methods are listed. See the following section.

For Linux installed on Vmware, the "beep" alarm will be issued in Shell due to incorrect commands or various reasons. It is not issued by the sound card, but by the motherboard, so it cannot be solved by disabling the speaker. The bedroom often sounds harsh. Today I found a solution on the Internet and noted it down:

Remove the # Before set bell-style none in/etc/inputrc, and then restart the system.

However, this method does not work, but the train of thought is correct. The value range of bell-style is none, visible, and audible. If you want to remove the alarm sound, it should be

Remove the # Before set bell-style visible in/etc/inputrc. If you do not have this sentence, add it yourself.

Remove linux alert sound

In fact, the kernel module pcspkr is the driver system horn module. Just disable it. Run sudo modprobe-r pcspkr on the command line. The best way is to add it to the blacklist. The method is as follows: add blacklist pcspkr to/etc/modprobe. d/blacklist to test again. There is no annoying system speaker sound.

1> shell alarm

Method 1

# Vi/etc/inputrc

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

# Do not bell on tab-completion

Set bell-style none

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

Method 2

# Echo "set bell-style none" >> ~ /. Bashrc

Note: The tab alarm sound in shell is removed. If there are other alarms, run the following command:

Setterm-blength 0

Or add it to/etc/bashrc.

2> register an alert when you log on to the machine group.

# Vi/etc/TPD/custom. conf

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

Or run the following command in the terminal.

In fact, grub is easy to edit. conf.

Add resolution settings after kernel/boot/vmlinuz-2.6.9-1.667 ro root = LABEL =/rhgb quiet:

Kernel/boot/vmlinuz-2.6.9-1.667 ro root = LABEL =/vga = 791 rhgb quiet
