Disabling the laptop keyboard in ubuntu 20.0.4
This is common problem we face during lockdown where keyboard starts to start working by its own. We need to disable the connected device and use only the external keyboard. The first command to list the input devices
xinput –list
the one that we need is
Disabling the keyboard
In order to disable the keyboard run the following command
xinput set-int-prop 16 "Device Enabled" 8 0
where 16 is the id for the input device
Enabling back the keyboard
In order to enable the keyboard back on run the following command
xinput set-int-prop 16 “Device Enabled” 8 1
Long term
In case of on start locking up we need to change the grub file
vi /etc/default/grub
try opening with sudo command for write mode.
check for this line
replace with following code
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash i8042.nokbd”
and then update the grub with command
update-grub2
After this we dont need to disable keyboard again.
# follow the guide with video
Disabling the code
view keycodes first
xev -event keyboard
after checking keycode
xmodmap -e ‘keycode 81=~’
