How to disable and enable keyboard on lenovo yoga?
You can use xinput
to achieve what you want. xinput
is a utility to list available input devices, query information about a device and change input device settings. Open a terminal and execute xinput list
- you will receive an output information which will read like this :
severus@Tux:~$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)]

Example :
To lock the keyboard : xinput --set-prop 11 "Device Enabled" 0
(11->device id from list)
To unlock it, xinput --set-prop <device id> "Device Enabled" 1
Caution! : Do not lock yourself out by locking all devices.

I have a Lenovo Yoga 300. It works well with Ubuntu, but I have a problem with a keyboard lock.
As it is a Yoga model, it has different modes of usage. When I turn the screen it should lock the keyboard for a normal usage of tablet or tent mode, but it does not lock it.
Is there any key or command that I could use to lock keyboard and unlock it when I need? Even if there is a program for it, that would be helpful.
