I have a Kinesis keyboard that I ideally like to use by placing it on top of my laptop. When I do that, I wind up pressing keys on the built-in keyboard with my external keyboard.

I've been playing around with the GUI keyboard controls and reading the ubuntu forums for a couple hours without really any forward progress. Even a hacky solution or a pointer to a good library for configuring multiple keyboards differently would be much appreciated.

This question came from our site for professional and enthusiast programmers.

You can try adding


to the GRUB boot line to disable access to the keyboard controller at boot.

It is possible to turn off the keyboard via 8042 commands without rebooting, but it's not really safe to do so; on some systems, this interferes with the memory management and causes a nasty system halt.

this is perfect for my situation, worked fine, though had a scary moment at login :) For anyone who happens on this post with the same question, I googled i8042 and found which outlines a pretty good post-boot approach. – David Nov 14 '12 at 9:34
An even harderware approach would be to use four stripes of Plast-Attach or any other type of cuttable adhesive plastic to build a keyboard holder under your Kinesis - two large strips to distance the keyboards, and two smaller strips to keep the Kinesis from slipping :-) – lserni Nov 14 '12 at 9:55
