I just updated to Ubuntu 20.04 LTS and my super key has lost its main functionality. Previously in Ubuntu 18.04LTS, I was able to click the super key and the applications drawer would show. Now it doesn't do that. I can still open it by clicking super+a but it's annoying that it doesn't do that.
I restarted my machine and still nothing.
It seems to be a gnome bug affecting multiple distros. Here's the thread in gitlab
super no longer opens overview (with dvorak keyboard layout)
This all happens under X11. Temporary solution is to change to Wayland if possible or change the most used keyboard layout to first position.
The developers are aware of the issue and it may be patched soon.
EDIT: As of today, Ubuntu 20.04 is upgraded from Gnome 3.36.1 to 3.36.2 and a updated system should no longer have this issue.
Just run
sudo apt update
Then run
sudo apt upgrade
Now gnome-shell --version should show:
GNOME Shell 3.36.2
Reboot system to apply changes: run sudo reboot or reboot manually.
