Autostart in KDE Linux
The Autostart folders in KDE/Linux
When you first log into your KDE session a large amount of application/system tray programs are automatically started. It can be quite hard to work out who is starting what, and in particular to make changes.
Applications are started by a .desktop file in one of the autostart directories.
The following folders are all checked for .desktop files:
I don't really know why we have so many.
Anything inside the /usr/ or /etc folder will have been installed by your distribution.
Disabling Autostart Files Provided By Your Distribution
KDE provides a wonderful tool in systemsettings ("Startup and Shutdown" -> "Autostart") for managing your personal autostart services (in either of the .kde directories) however it doesn't cover systemwide autostart scripts provided by your distribution packages, or created by the gnome apps.
Sometimes however it can be useful to override your distribution autostart preferences, for example I don't like having the printer-applet running as I don't own a printer, but it seems a shame to uninstall it in case I need it.
The Wrong Way to Disable Application Autostart
Contrary to what most people actually do, the correct way to disable service is not to delete the files your package manager has installed. There are a few reasons for this:
- It will affect all users on the system
- It's an abuse of your root access (which you may not have)
- As soon as the package upgrades, the file will be restored and it will come back to autostarting again - which isn't what you want
The Right Way
The correct way to disable a package installed is actually to copy it to your personal autostart folder. Anything of the same name in ~/.kde/share/autostart overrides the .desktop file in the default installations. Once we have copied the .desktop file we can make changes.
Add the following line to the .desktop file you have just copied:
A personal opinion
I think everyone would agree we could do with normalising how many autostart folders we have, which would be easier to do by us losing our kde specific ones and following freedesktop standards.
I also wonder if disabling systemwide autostart services in the manner listed above could be handled, it seems do-able to me. If someone comments approving it, I'd try and see if I can make a patch.
I'd also like it if developers really think hard about whether something actually needs to have a system tray icon constantly loaded on startup or whether it can be an easy to find seperate application for a user to run. It provides less visual clutter as well as a faster initial load time.
The Freedesktop Autostart Spec - note this doesn't actually cover the real state on a Linux box, only what it should be doing.
