Disabling Nepomuk and Akonadi

After upgrading to KDE-4.7.0, I feel that Nepomuk and Akonadi are very annoying. I always get notification about Nepomuk and some messages about Akonadi when I quit from KDE. Since I don't use Desktop Search and KMail anymore, I have decided to turn Nepomuk and Akonadi off.

Disabling Nepomuk
I follow these steps to disable Nepomuk:

• Go to System Settings --> Workspace Appearance and Behavior --> Desktop Search
• Untick "Enable Strigi Desktop File Indexer" and "Enable Nepomuk Semantic Desktop" under Basic Setting Tab
• Choose "Ignore all removable media" on Removable media handling and also make sure all folders are left unticked in "Customize index folders ..." under Desktop Query Tab
• Select "Disable Automatic Backups" on Backup frequency under Backup Tab
• Go to System Settings --> Common Appearance and Behavior --> Application and System Notifications --> Manage Notifications
• Under Applications Tab, select "Desktop Search" on Event source and make sure all states are empty
• Do the same for "Nepomuk file watch service" and "Semantic Desktop" on Event source
• Quit System Settings

Disabling Akonadi
For disabling Akonadi, open the terminal then enter the directory ~/.config/akonadi/akonadiserverrc and set the value of "StartServer" on [QMYSQL] to false.

[QMYSQL] 
... 
StartServer=false

After finishing all steps described above, restart the KDE. Nepomuk and Akonadi have been disabled.

Note: I configure my System Settings to Classic Tree View (see picture below).
