Contains a simple shell program to enable or disable Internal Keyboard of a laptop in Linux.
copy ikbdop.sh to your local device (maybe into ~/.local/bin/) and use it to disable and re-enable the Keyboard while using the X Display Server.
This is currently work in Progress... you are free to contribute.
This is currnetly still in development and/or testing and i am open for contributions
~$ sudo pgrep wayland --count will tell you if there are running processes whose name contains wayland.
Your are most likely running wayland if the result is greater than 0.
Use ~$ sudo libinput list-devices to get an overview over all input-devices that wayland can access.
You can also use ~$ sudo evtest to determine which device is which.
Generally "AT Translated Set 2 keyboard" is almost always the internal keyboard and "SynPS/2 Synaptics TouchPad" is the internal TouchPad.
Please take note which device you want to disable and what exact "/dev/input/eventX"-Path it has.
If you know what to search for you can use for example ~$ sudo libinput list-devices | grep --after-context 1 "AT Translated Set 2 keyboard" | grep Kernel | awk '{print $2}' to get the "/dev/input/eventX"-Path without having to copy-paste.
Use ~$ sudo udevadm info --attribute-walk --path=$(udevadm info --query=path --name=/dev/input/eventX) | grep --extended-regexp --regexp='looking at parent device .\/devices\/platform\/[A-Za-z0-9]+\/[A-Za-z0-9]+\/input\/input[0-9]+.:' | awk '{print $5}' | sed 's/://' | sed 's/^./\/sys/' | sed 's/.$/\/inhibited/' to get the "/sys/devices/platform/[...]/input/inputX/inhibited"-Path
Watch out that you dont lock yourself out of accessing/controlling your device when you deactivate your touchpad and/or internal keyboard and have external devices (or a touch screen) at hand to interact with the device and re-enable the internal devices.
Check current status of the device
~$ cat /sys/devices/platform/[...]/[...]/input/inputX/inhibited
Output 0 is not inhibited (device is not ignored by the kernel). Output 1 or higher is inhibited (Kernel ignores inputs from the device).
Disable the device (as root)
~# echo 1 > /sys/devices/platform/[...]/[...]/input/inputX/inhibited
Re-Enable the device (as root)
~# echo 0 > /sys/devices/platform/[...]/[...]/input/inputX/inhibited
~$ nano ~/.local/bin/convertible-mode.sh
#!/bin/bash
## Syntax
# To enable Convertible Mode (inhibit internal Keyboard and Touchpad) use './convertible-mode.sh enable'

make the script executable
~$ chmod u+x ~/.local/bin/convertible-mode.sh
Create a new Group "convertible", add yourself to the new group and re-login or reboot and check your groups.
~$ sudo groupadd convertible
~$ sudo usermod -a -G convertible USER
~$ groups
Allow the new Group to execute the new Script with sudo without entering a password.
