Ctrl-Alt-T stopped working after installing GNOME Shell on Ubuntu 18.04

Go to Settings -> Devices -> Keyboard, then add Ctrl + Alt + T if it does not exist.

Upgraded to 18.04 from 16.04 ; kept my preference for the Unity desktop. But couldn't open the terminal with a key combo despite checking the shortcut in the checked answer.

  • Install compizconfig-settings-manager
  • Run ccsm
  • Turn off the "Commands" plugin

This resolved the lack of ctrl-alt-T, Vol +/-, all the other extended and media keys on my keyboard.
