Ubuntu:Disable Laptop Internal Keyboard

 

I am using Dell Laptop my laptop internal keyboard

acting weird insense it make sound from nowhere &

causing deleteting of folders & files abruptly without

me pressing any keyboard.

Also I observed that when I am typing in some document

it start deleting content,I try to replace it from technician

but still it behaves in same way.

I decided to disable it as I have bluetooth keyboard & mouse that

can do the treak.

Here is How you can disable laptop internal keyboard in Ubuntu,

same method should work whereever their is GRUB.

Edit /etc/default/grub

sudo nano /etc/default/grub

In this opened file look for

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Now replace this line with following line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nokbd"

We need to regenerate grub.cfg so that our changes will take effect.

Run

update-grub2

Now you can reboot the laptop your Laptop Internal Keyboard will be disabled

You have not worry of your file & folders getting deleted abruptly & nor your

content of opened text in text editor will get deleted nor some weird keyboard

sound which tell some keyboard key is struck.
