I am trying to improve my system performance by removing some daemon/Services.

On my Desktop PC i need to stop some daemons/services Which are Installed by Default in Ubuntu From auto starting . & manually start when ever i want to .

Can any one provide list of daemons/services which are installed by default in Ubuntu & it will be ok with manual start just like i did with Ubuntu one

These are few Services/Daemons i have never used it on my Desktop & Uninstalled it printer , scanner ( saned ) , bluetooth .

I have Noticed at shutdown that acpi Daemon take 2 to 3 seconds (Advanced Configuration and Power Interface) in help its shows that u can actually turn it off . can i Uninstall it & is it safe ? if yes how ?

modem-manager takes up to 2 seconds at shutdown & fail every time pc reboot/shutdown

i have managed to reduce at least 3 to 4 sec at reboot/start Ubuntu , i have made some script so when ever i need that service i just click on script & its on . example vmware script

Note: dont want to use extra tools like chkconfig , rcconf .

Use chkconfig You can see what services are running and disable desired services from being started at boot time, and of course manage the state of a service while your OS is running:

    # sudo apt-get install chkconfig
    # sudo chkconfig -s <service> <state/runlevels>

And of course :)

    # man chkconfig

  • Sir dont want extra tools , chkconfig , rcconf – One Zero Feb 16 '12 at 14:30
  • I understand, *chkconfig* has a *very small* footprint, it has no dependencies and will only use *70kB* of additional disk space after installation. It is the configuration daemon management tool of choice for distributions such as Redhat, so it is highly functional, secure & reliable, not to mention it will do exactly what you require :) – kingmilo Feb 16 '12 at 14:52

  • Are you sure chkconfig is useful on Ubuntu? – Marky Feb 07 '13 at 17:25
  • I don't understand the question. – kingmilo Feb 13 '13 at 13:59
