-The ''tracker'' file indexer will run by default in some cases, even if it doesn't show up in your startup applications.

If that is the case, and you want to disable it, run ''tracker3 reset --s'' to stop the processes and remove all indexes, if you want the service completely disabled.

 +The reason why you may want to disable these services: even though a desktop search engine sounds like a good idea, but indexing all of the big data disks as soon as you access them, takes a lot of network bandwith, cpu time and memory, and storing the index of the disks will probably exceed your home disk quota.

 +===== Evolution =====
 +Evolution is a mail/calendar suite, and can be a very useful tool, if you use it. Unfortunately, a lot of programs are started in each user session, even if you don't need them, or even if you have never used evolution. These programs don't show up in the usual session program dialogs, but from the commandline it is possible to disable them:
 +
 +  systemctl --user daemon-reload
 +  systemctl --user disable --now evolution-source-registry
 +  systemctl --user disable --now evolution-calendar-factory
 +  systemctl --user disable --now evolution-addressbook-factory
 +  systemctl --user disable --now evolution-alarm-notify
