I am using Ubuntu 20.04. Yesterday while looking for a package, I found that Evolution was due for an update. Since I never use it, I thought I would uninstall it. Being I was not aware that gnome is now being used as Ubuntu default desktop, I uninstalled other things I thought were associated with that as well.
Now I am getting this message from HPLIP.
No system tray detected on this system. Unable to start, exiting.
There were several programs that had icons on the system tray that are no longer there that I would like to have back.
Additionally, the side dock where favorites are kept no longer autohides and pops out when I run my mouse up against the left edge of my display. I now have to go click on the "Activities" link at the top left corner of the display. I have gone into settings numerous times and set the dock to autohide and every time I go back the setting has been disabled again. I presume this is because the feature is no longer installed.
Does anyone know exactly what package I may have uninstalled that I need for these two issues?
I did re-install a few gnome packages which fixed some things, but not these two.
