Some easy way (one click) to switch off Akonadi + Nepomuk + Strigi

Feature state

openSUSE Distribution
Rejected Information

Description

Please help us - the users, who decide to use in the real business the Linux PIM management.
Please make possible for us to choose - will we use the Semantic Desktop or just would like to switch it off for some reason.

Since years the idea of so called Semantic Desktop is taking huge time and efforts but results still are unappealing.
I admit the work of the developers and any one should be thankful for their efforts in making KDE the best free desktop ever. But... please give some chance to users to choose what they need and prefer.

User benefit:

Since years this Semantic Desktop experiment still can not provide enough good results to use in the real business life. Now with the openSUSE 12 thanks to Akonadi + Nepomuk + Strigi the elegance and speed of the Linux Desktop is gone and we have some Desktop like Windows. This is because most of the hardware potential is used just for internal processes of the Semantic Desktop. This way the Desktop is getting slow and unresponiive, the HDD is running mostly all the time, a lot of RAM and HDD is used, and now KMail get buggy slow, etc ... Let users can have one unbroken PIM Management for their real life until the Semantic Desktop can provide the needed experience. Let those who prefer the Semantic Desktop in its current condition can use it as he needs.

Usecase

Ideally we need one additional item in Kickoff -> System Settings. Now there is available the item 'Desktop Search (Nepomuk/Strigi)'.
May be some button to make possible to switch on or off the Semantic Desktop will do the job?
Or please provide in the already available item 'Desktop Search (Nepomuk/Strigi)' a software button or any other easy visible tool to switch off or on all this Semantic Desktop components.
Please possibly change the related software to be capable to work with or without all this Semantic Desktop technology.
Let make possible for the end users to decide whet they need - a Desktop with or without this Semantic Desktop technology.

I couldn't agree more!
Semantic desktop is something I do not need, and I don't know any of my colleagues who needs or uses it, and in my environment (theoretcial physics) nearly everybody uses Linux/Unix! I'm fully productive with locate concerning looking for files, when I forgot, where I've saved one before. Even when not using the semantic desktop by switching off strigi, akonadi always started some business, blocking memory, CPU, and (the least issue) disk space, and this although I've switched off as much akonadi services as possible in the desktop configuration tool. That's why I deinstalled as much of akonadi as I could without violating depencies and the functionality of my kde4 desktop, which without akonadi is a great desktop with a high efficiency and a high level of configurability for the user. It's really a pity that perhaps putatively new Linux users come to the conclusion that kde is not better than Windows concerning responsiveness and efficiency and then perhaps they don't use Linux for that reason.

In addition after a very long time, I switched from kmail, knode, and korganizer to thunderbird for all my PIM, just for the reason of making the system highly unstable and unusable for daily work. The most annoying thing is (was?) the instability of kaddressbook. Not only did I loose my data stored in there for years (under kde3) without any loss before all this akonadi stuff entered the same. In addition, the function to build groups for mailing to a specific list of people hasn't worked anymore. Now, I'm happy with thunderbird, and I'm not so sure whether I ever switch back to kde-pim.

I haven't tried 12.1 yet, but in 11.4 you just need to go to KDE's Configuration tool and click on "Desktop search". There you can enable/disable both Nepomuk and Strigi with a single click each. You can also change the way they work to make them less intrusive.

This holds true for 12.1 also. My understanding is that Akonadi is required for many parts of KDE - Knotes on up. But I tested it without the Nepomuk ans Strigi services running, and by itself, Akonadi is relatively lightweight.
-A-

And yet Akonadi will
still run in the background if there as an application or widget that calls it, even without the user's knowledge. This also caused the great annoyance for many users (as seen in a long KDE bug report) about the nagging notifications from Akonadi that "Nepomuk is not enabled!" KDE developers can't get it over the heads that a lot of users don't use/like/need/want a "Semantic Desktop". The truth hurts.

I agree. There should be a simple way to disable Akonadi/Nepomuk/Strigi
entirely . If the user loses some features in Kmail or some other application/widget, then so be it. He chose the path of speed and simplicity over features he never uses.

1. If an application needs it, what do you want to have happen? If it's a dependency of something, it's a dependency. If you don't want to use Akonadi, you have to not use anything that depends on it. It's part of the PIM suite and isn't churning your hard drive like Nepomuk. It's just a unified database, using MySQL by default I believe.
2. You can type "kcmshell4 akonadi" at a shell prompt and get an akonadi configuration dialog (in 11.4 after install akonadi would start another akonadi_contact service with every boot and this was needed to be used once to kill them and stop the behavior - I'm not sure if the bug was ever fixed). Here you can modify or kill akonadi resources, change its database backend, etc. Don't complain if you break KDE entirely though all in the hope of shutting down a front-end for MySQL which is probably already running on your system anyway. :-)

I just set up a VirtualBox machine with 11.4 and imported my K-Mail emails into it and launched the 12.1 upgrade process. If KMail2 fails to import my e-mail in the VM I'll probably be back here complaining more than anyone else. :-) On that front if there are import problems they should have just left KMail 4.4 in as they did for 11.4, but that's another openFATE issue.....

Well, in my opinion, Akonadi and friends shouldn't be requirements at all. I'd change the Requires to Recommends, and make the installation of the packages optional.
My rationale is that in underpowered systems, Akonadi, its database, its indexing processes, they're all a serious performance drain. I have an old P4 with 1G RAM running 11.4 which sufffers from it, every user has around 64-128M of wasted space in their home due to Akonadi's database, and I have to manually and regularly clean it up, even with the service "disabled".
It's clear that disabling the service only does so partially, so it should be possible to flat out uninstall it. When I tried, lots of core KDE packages were depending on it (I'll muster a list later). So packages should never really depend (Require) Akonadi, only be improved by its presence (Recommends).

Of course this may need requiring apps to be patched.

Ok, uninstalling akonadi runtime plasma-addons, uninstalling libakonadi wants to uninstall python-kde4, kdebase4-workspace, NetworkManager and kwin which seems quite excessive.

Kmail, kipi, kdepim too want to be uninstalled, among others, but I can see how making those not depend on akonadi could be difficult. If at all possible, though, it should be tried.
