I tried following the advice in this thread to set the compose key: https://discourse.lubuntu.me/t/how-can-i-set-compose-key-in-lubuntu-lxqt/421
But, it doesn’t work. I tried setting the key, no dice; restarting the computer didn’t make it work either.
Anyone know how to do this? I use it all the time, so it really slows down my work to have to go into the special character menu in Libreoffice, for example.
ETA: apparently my choice for “Keys to change layout” isn’t “sticking”. I go into the menu, select R-Ctrl, click “apply” and close the menu, then if I open the menu again the option says “none.”
