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
