 This article is out-of-date, and needs to be updated.
Please see the talk page for discussion.

Services are programs that run in background, invisible to the user, and do some useful work such as maintaining Internet connections, checking for email, playing sounds, etc. Sometimes, services are called daemons. To see the list of services currently running on your tablet, you can use the following:

  • ps, top, or htop command line utilities, invoked from XTerm.
  • CPU Load desktop applet (found in Extras).
  • Services configuration applet (found in Extras).

Just like any other program, a service can be killed with the kill command or the appropriate button in the CPU Load applet. To disable a service (so that it does not start up after the next reboot), you can use the Services configuration applet. Be aware though that killing or disabling some services may seriously damage your system. Avoid it unless you are absolutely sure you know what you are doing.
