I need a way for call agents to be able to change keyboard layout to the language they need via dedicated desktop shortcut icons. E.g. Chinese agent double-clicks icon "chinese language" and he gets it, Ukrainian agent double-clicks "ukrainian language" etc. so that everybody gets their special language characters.
I tried running a script which rewrites /etc/default/keyboard e.g. from "us" to "gb" keyboard and seemed to work. But found out only root can do that and call agents should not be sudoers.
I was looking for a script to bring up Keyboard layout window, that would be a nice way as well, agents could then just scroll, find their language and change it easily.
I googled intensively and couldn't find anything real. Does anybody have experience with this? Thanks!
