I was on a very early version of Mate and updated it as far as I could. However, on logon the keyboard is fine but once logged on, even though UK Dvorak is selected, the map is not British. Instead of ASDFGH it's more like AOEUIDH and I've tried installing console-common and that hasn't worked.
Any ideas please? Hopefully things I can click on because typing is difficult and secure passwords are a nightmare!
