After installing Lubuntu on an older laptop (C500 Presario Compaq) I have found that I am completely unable to change the keyboard layout! I have tried the following:
Select keyboard from Keyboard Layout Handler in taskbar - FAILED as it does not exist.
run setxkbmap -layout us - this works, but only until next reboot - FAIL
echo '@setxkbmap -option grp:alt_shift_toggle "es, us"' | sudo tee -a /etc/xdg/lxsession/Lubuntu/autostart - FAILED makes no difference, even if I set to "us, us" as I don't want to toggle, just want $$%$^$ us language keyboard.
Older versions of Lubuntu had preferences->lxkeymap but not in latest version, so any attempt to use that - FAILED
Tried to edit /etc/default/keyboard. can see it's set incorrectly to uk, but cannot change it through GUI as directory is write protected. Cannot change via terminal window, because the keyboard is too screwed up to run vim correctly - FAILED
Go to Menu->Preferences->Keyboard input Methods. - FAILED it does not exist. Only a Preferences -> Keyboard and Mouse, and the keyboard section contains nothing useful.
Honestly, how hard can it be to configure a keyboard?!! I am running the very latest version of lubuntu with all updates as at 23 March 2017.
