Volume up-down, calculator, ctr-ALT T, windows key + A and more, not working

[kickass]

@fossfreedom

gnome settings -> region&language and there, click on “manage installed languages” then changed “keyboard input method system” to none instead of ibus. Logout and login.

Seemingly this fixes this issue. Can anyone do this and verify?

I just did this after the volume hotkeys stopped working on a fresh 18.04 install.
Worked a treat!
