How to turn off laptop keyboard
Half a year ago I accidentally spilled soda on my laptop keyboard. Of course I’ve cleaned and dried it but once in a while some keys press themselves. The issue became annoying when I was watching movies and mplayer just kept turning off. I didn’t want to replace broken keyboard, because I already use usb one. I spend half a day investigating and as it came out it’s not all that easy to turn off laptop keyboard.
Here are solutions I’ve found:
- Disconnect keyboard physically – not an option for me, I still want to use that keyboard when I’m out
- Edit your /etc/X11/xorg.conf so your InputDevice section looks like that:
Section "InputDevice" Driver "evdev" Option "Protocol" "evdev" Option "Device" "/dev/input/event6" Option "evBits" "+1" Option "keyBits" "~1-255 ~352-511" Option "Pass" "3" Option "XkbModel" "evdev" Option "XkbRules" "evdev" Option "XkbLayout" "pl" EndSection
Where /dev/input/event6 is your usb keyboard (you can find out that by looking at the symlinks in /dev/input/by-id/).
You may want to adjust layout option.
Well, it almost worked for me. I couldn’t type my regional characters using alt-char combination.
It would’ve worked if I had ‘evdev-managed’ in my kde keyboard layout settings.
I didn’t have it and other layouts messed my layout (my up arrow was printscreen, left arrow was alt etc.), so I had to turn it off.
- Make two files:
#!/bin/bash echo -n "manual" > /sys/devices/platform/i8042/serio0/bind_mode echo -n "psmouse" > /sys/devices/platform/i8042/serio0/drvctl
#!/bin/bash echo -n "auto" > /sys/devices/platform/i8042/serio0/bind_mode
Execute them from root prompt (executing with sudo won’t work).
I don’t know how portable that is, so you may have to find out if you have serio0 and if it is your laptop keyboard. My laptop is Fujitsu-Siemens Amilo M3438.
It disables laptop keyboard in both X and console.
