I have asked a related question in different sites such as here in German and a related thread here, a different case in the latter though. The
# dpkg-reconfigure console-setup is firing
WARNING: Unknown X keysym "dead_belowcomma", some bug?
I almost solved the question here, basically:
"/etc/default/keyboard" -modification and one-line
"$ setxkbmap -option grp:caps_toggle -variant dvorak-intl,nodeadkeys, us,de,no &" -- but the layout-settings get reseted after reboot. I use Debian but I believe the same settings apply to Ubuntu hence asking here.
So how can I get settings to stay after rebooting? Or
# service gdm3 restart?
Or better how can I configure international keyboard -layouts system wide?
What about user-centric keyboard -configuration?
