loadkeys dvorak: Couldn't get a file descriptor referring to the console
Within a KDE session, before I had an opportunity to configure keyboard layouts within KDE, I opened a konsole and tried to load a dvorak keyboard:
$ loadkeys dvorak
Couldn't get a file descriptor referring to the console
I don't know why, nor how/when to use loadkeys.
apparently, loadkeys should be added to the .bashrc file, so that the keys are loaded when logging in.
