And more to the point, can I kill them off without problem?

I'm going through the process table to find un-necessary processes and I haven't found any useful documentation about kwrited or knotify that makes me think they perform any function that's useful to me.

And on that subject, do I really need this lot, configured in systemsettings?

• KDED Global Shortcuts Server
• KDED Favicon Module
• Network Status Daemon (I have a static network)
• KDED Remote Base URL Notifier
• KDE Time Zone Daemon
• Free Space Notifier

I think kwrited can be disabled in system settings.
knotify4 processes notifications of KDE applications, so even if you kill it, it will be restarted by the next notification.
No idea about kaccess

I think those are all plugins of KDED, so no additional processes.
You don't need the shortcuts server if you don't use shortcuts, the favicon module id you don't use a KDE browser, the network status daemon probably not if you don't need applications to change state if connection is lost (cable unplugged, etc), no idea about the last three.

The Free Space notifier just notifies you when you are running low on HDD space. It should be perfectly safe to disable.

Well, I've killed the lot off[1] and so far[2] haven't seen anything not working.

Startup services were easy enough, un-ticking them in systemsettings (though for some reason the Time Zone Daemon ignored this and ran anyway.

The on-demand ones can be disabled by editing their .desktop files, but NetworkManager, kaccess, kwrited and knotify4 had to be disabled by removing their execute bit.

Not in itself a huge difference to system resources, but every little helps and every un-necessary daemon removed makes it a little more secure.


[1] Actually disabled everything visible in on-demand services and startup services apart from the KSSL Daemon Module (without which Kmail can't talk to SSL-enabled mailservers)

[2] Early days yet...

KNotify4 is required for delivering all notifications in KDE, including Sound, Text to speech, visual, command execution and taskbar flashing so you may experience problems involving it being disabled.

Sounds like a win to me.

The only sound I want to hear out of my computer is the audio I'm playing through Amarok or Audacious (both still working without knotify4). I don't need text to speech, don't even know what visual is, don't seem to be having problems executing commands from xterms, and taskbar flashing is just annoying (I've been looking for a way to disable it in KDE4 anyway).

So not only have I got rid of an unnecessary process, I've disabled some pains in the **** as well.

Evidently knotify4 isn't required for taskbar flashing, as that annoyance is still evident even without that daemon running.

Oh well...

Google keeps leading me to this page and although it is a bit dated I'll leave my findings here for all the others that find this page and mis the information about kaccess.

/usr/bin/kaccess is part of the kde-workspace package and relates one-on-one to the settings in the Accessibility configuration screen in the System Settings.

To stop kaccess from starting at logon, you have to disable all options in the Accessibility dialog. I regret having to stop it because it has a really cool feature to make a beep every time I accidentally strike Caps Lock, but there is a bug in kaccess that makes it lock a pulseaudio sink. This is related to error messages in .xsession-errors:

Code: Select all

kded(2508)/kmix sink_input_cb: Ignoring sink-input due to it being designated as an event and thus handled by the Event slider

and a few other small issues (probably all related to the same little bug).

I'm running KDE Plasma 5.8.2, but I noticed running knotify4 process. Is it an artifact of older Plasma 4 installation, or it's still used in Plasma 5.x?

It's used/started by KDE4 *applications* when they want to display a notification...
