I ran into today for the first time my screen not showing the Z menu button, nor any of my designated favorites. There was one button (I don't know the right name) with two layers of rectangles. It shows open apps which I could choose among. I couldn't get back to the normal taskbar and the general Z menu button. I was able to Restart, and after that all looks okay.
This somewhat resembles in MS Windows when Explorer crashes. If you know enough to Ctrl-Shft-Esc to get Task Manager up, you can manually invoke Explorer again. If that is the type of thing I ran into in the Linux environment, what would be the equivalent way to re-start the overall desktop environment with the taskbar re-populated? Sorry to bother folks if this is common knowledge among Linux users.
If what I've run into is a bug, does it seem a Zorin package bug, or a component that Zorin folks didn't write but just included? Should I be reporting elsewhere?
It sounds like gnome-shell crashed.
When that happens, you can try hitting alt+f2 to bring up a launcher dialogue, then enter in the letter r (for restart) and hitting enter key to restart the gnome-shell.
If it happens more than once, please update this thread with that info and if you can recall what processes you were doing that may relate to why the shell crashed.
Until you realize it is actually a chocolate wrapped in tin foil...
You're right. Due to Zorin OS 16 currently being in Core only, I am neglecting 15.3 Lite. I need to stop doing that...
That being said; the description the O.P. gave describes Gnome Behavior...
Thanks for the Alt-F2, r tip. Gnome handles the general environment similar to in Windows Explorer handles it. If I run into recurrence I'll jot down what was going on right before then.
I think today I had been in a Zoom conference, with Zoom maximized. At the end of the conference I clicked Leave. I think it was right after that I noticed the effects of Gnome crashed.
Please update this thread when it happens again- it may have just been a one time thing.
But since you mentioned Zoom and I have encountered others saying Zoom crashed the shell, it is curious.
