I am using a DELL INSPIRON laptop. Unfortunately there occur an internal problem on the keyboard of the laptop. It may short any key which self-pressed all time and reasonable some problems which is very awkward. I use ubuntu 14.10 now and before I used windows 7.
I use this command at terminal
xinput --list
xinput float (#id) /* #id is get from the list*/
It works but regain the previous setting i.e. enable again when shut down and and restart. But I need to permanently disable the internal keyboard and when i need it back again then enable it.
Is there any procedure to do it?
