Every now and then processes around the unwanted ‘tracker’ spyware eats my CPU and turns my laptop into a loud hairdryer.
Unfortunately it’s often impossible to uninstall it without loosing half the desktop-related packages.
This is how to stop it once and for all (per user, as user):
systemctl --user stop tracker-extract.service
systemctl --user stop tracker-store.service
systemctl --user disable tracker-extract.service
systemctl --user disable tracker-store.service
rm -rf ~/.cache/tracker/
