Over the last week, I upgraded all our household computers from 20.04.x to 22.04.1. Everything has gone well until this morning, when I upgraded my personal workstation. Now I have no… what's it called? The button used for choosing to reboot, shutdown, launch programs, etc. (On my "Redmond" layout, that's usually in the lower lefthand corner of my screen.)
What will restore this button?
Thanks in advance.
