When inspecting the running processes on Ubuntu 16.04, I noticed few processes of Evolution.

However, when I opened Ubuntu Software Center to uninstall Evolution, it's shown as not even having been installed.

Why is this? How can I get rid of Evolution? I don't want such processes which I never use, unnecessarily consume RAM.

  • Evolution MUA (mail user agent) software is not the evolution data-server you see in the process picture you added. The evolution data-server is part of gnome, the evolution mua is a mail program you can add to gnome (or other desktop). – guiverc Jun 4 '19 at 13:04

That's the evolution-data-server package.

Description: evolution database backend server
 The data server, called "Evolution Data Server" is responsible for managing
 mail, calendar, addressbook, tasks and memo information.

e-d-s is part of the Gnome and Unity desktops. It runs the integrated calendar and address book.

  • So can I safely remove the evolution-data-server? I hope it'd have no effect on the time and calendar features that appear on the top right edge of the Ubuntu screen? Is removing it as simple as sudo apt-get remove evolution-data-server? – Nav Jun 4 '19 at 15:49
  • Can also be "safely" removed in later Ubuntu versions that are using Gnome Shell. There, it takes away your entire desktop and your login manager gdm. Safe it is, because you are left with an intact Ubuntu system. However, a restart leaves you to a terminal rather than bringing you on your desktop. That is fine, but only if you want that. – vanadium Jun 5 '19 at 15:05
