After I upgraded to 18.04 from 16.04, Super+Space started showing numbers on icons on unity launcher instead of switching between languages. How can I fix that?

Keyboard -> Shortcuts -> Typing -> Switch to next source is configured to Super+Space.

  • Can you check is compizconfig-settings-manager or unity-tweak-tool is installed? In case Yes, you can try found solution here: askubuntu.com/questions/846245/…

  • @S_Flash, thank you, compizconfig was installed and helped. The only weird thing now is that when I switch between 3 languages (which takes about 1 second), keyboard shortcuts menu (hint) pops up. I'm really starting to hate 18.04 :(

  • Is no reasons to hate 18.04, because Unity is not native for Ubuntu 18. Now we need focus on GNOME as native shell for Ubuntu 18+. Try search solution with keyboard layout switch delay here: askubuntu.com/a/353809/881020 I hope it can help.

Install compizconfig-settings-manager & look in the unity plugin > Launcher, see screen. The x button on far right sets to default which is Super & enabled.
