Reminders:
1. "removepkg akonadi" works
2. To disable Strigi and Nepomuk
- in the K menu, choose System Settings (if you are not in kde, launch systemsettings in an xterm, konsole, whatever)
- in the Advanced tab, choose Desktop Search
- in the Basic settings, uncheck Enable Strigi Desktop File Indexer, uncheck Enable Nepomuk Semantic Desktop and hit Apply.
3. KDE-4.3.1 is not shipped with Slackware
Here KDE-4.2.4 works -- without Akonadi and with Strigi and Nepomuk disabled
Did you look at the logs (/var/log/messages, /var/log/syslog and /var/log/X.0.log) to diagnose your problem ? May be it has nothing to do with Akonadi, Strigi or Nepomuk
PS I am not a KDE user (I prefer Fluxbox) but have KDE-4.2.4 installed, use a few KDE applications and so far all goes well.
EDIT. Sorry but I didn't see this
other thread you started before posting. Otherwise I would have only asked the question about diagnosis. Seems like when something go wrong, you don't spend so much time to understand what happened, do you ?
