I use Ubuntu with two input languages, switching between them with Super+Space.
I have upgraded Ubuntu to 21.10, and during the installation it has asked to select another key combination, not offering Super+Space, so I chose next commonly used combination left Shift+Ctrl.
Now the problem - both combinations are active, and all existing key combinations that involve Ctrl+Shift stopped working. How do I reset it all back?
I use Ubuntu on XOrg (not Wayland). In the system settings it still shows Super+Space as the key combo. How do I bring up that window from the upgrade process to remove the Ctrl+Shift assignment? Was it Wayland keyboard settings?
