> Why can't I disable the desktop search? After some hours googling I managed to kill most of Akonadi and Desktop search ...
That's not the way to do it. Maybe there are some GUI ways to disable it, but in effect, your ~/.kde4/share/config/nepomukserverrc should have:
[Basic Settings]
Start Nepomuk=false
[Service-nepomukfileindexer]
autostart=false
[Service-nepomukstrigiservice]
autostart=false
... and some more stuff...
Edit the file yourself, as I did, and the indexing service won't be started the next time you login on KDE.
I've implement this fix previously - and a few others earlier in the Akonadi/Nepomuk and whatever issue cycle - KDE has in the past prided itself on configurability. I'd have thought the buggy, resource hogging and much maligned desktop search facility would have been a prime candidate for a simple checkbox in the systemsettings interface. This has now appeared but I'm not sure by itself how good that checkbox is at preventing the shocking overuse of system resources for desktop search that was becoming the KDE signature.
I see that the devs have been trying to create a new paradigm in desktop use but sacrificing the user base on that altar seems strange for so little benefit.
