You don’t have to turn it off.
It is only started if some application uses it.
system settings > (search for ‘akonadi’)
You cannot turn it off there. To really disable it, you’d have to edit a config file directly, or uninstall it (this will uninstall all applications using Akonadi as well, like the whole KDE-PIM suite).
But again, this is not necessary. Just don’t use any Akonadi-based applications, and it won’t run.
Yes. As I mentioned, this was probably configured by the Akonadi-Migrator and taken from the old KMail1 config.
Wolfi323 the /home/uli folder is still on the computer and when I log in - the NAS is mounted at the mount point ulimnt.
So the NAS mount is irrelevant. Akonadi’s cache (i.e. the MySQL database) is in ~/.local/share/akonadi/. If this is on your local hard disk, you should be fine.
Would my system (where the stored emails are on the NAS) still work when baloo-pim is uninstalled?
Yes.
Baloo is KDE’s indexing/search system.
If you uninstall baloo-pim, it just won’t index any PIM data like Mails.
You can still search via the search bar though, it’s just not using the baloo index obviously.
Obscurant - I think I need akonadi when I use kmail on a different location?
You need Akonadi if you use KMail at all. KMail is based on Akonadi, like KAddressbook, KOrganizer, KNotes, KJots, KAlarm, …
BTW I am using the version 13.2 (latest version with the default KDE desktop on a 586 machine).
Right. Baloo is new there. In earlier openSUSE versions, Nepomuk was included. That was replaced by Baloo in KDE 4.13 (13.2 comes with 4.14), which actually should work better. But Nepomuk’s indexing was disabled completely by default in openSUSE, including the PIM-Indexer.
Maybe the problem would disappear after the initial indexing?
You can disable indexing on a per-folder basis too. Just right-click on the folder, choose “Folder Properties” and switch to the “Maintenance” tab.
