Hi,
I installed many times the Ubuntu Mate Edition in the german way. Any time if I go to in the terminal, the keyboard layout input is only in US. When I run the “sudo dpkg-reconfigure keyboard-configuration” command, it only setup temporally in “de_DE.UTF-8”. I have to repeat anytime when I goto in the terminal.
The only stupid solution is, if I add in the system settings / keyboard / language: United States, US-Englisch, then my german keyboard layout will be stay active in the terminal.
Regards…
