HOWTO: Disable the NTP sychronization process during usplash.

[Muhammad]

Many people have reported that NTP Synchronization slows down or lags the booting process, I thought I might as well post a mini-HOWTO. :)

System -> Administration -> Synaptic

Click Search and type "ntpdate" in the search box.

Right-click and choose "Mark for Removal"

NOTE:This will also remove the Ubuntu-minimal, but don't worry, it won't cause harm .

Alternate Method:

sudo apt-get remove ntpdate

Congratulations, the NTP will never cause you annoyances again!

If you don't want it to be permanent, you can just remove its executable permission:
sudo chmod -x /etc/init.d/ntpdate

In Gnome, you can also deactivate it going to the menu option System -> Administration -> Services

Another, less "removing" solution is to use the following command, given all over the forums:

sudo update-rc.d -f ntpdate remove

That just removes it from startup. Worked for me!

thanks worked well, the one above me :)

nice one oblib, very chic way :D

I'd recommend downloading the bum package. It is a lot easier than update-rc.d or any other method.

Strange thing happened when I did like that: during next boot the boot process stopped and computer power went down. When this happened, last line was: calculating module dependencies... I had to boot failsafe, and put ntpdate back to be able to normal boot (this ntpdate fails, btw. That was the original reason to remove it...)

deactivating the service didn't help :( ubuntu still tries to to sync the clock during boot.

I removed ntupdate but it removed ubuntu-minimal with it, why does it do that? I was afraid it might of affected something else so I did apt-get install ubunutu-minimal and it installed ntupdate back again. Anybody know why?

[mlomker]

That's a metapackage, so you can safely remove it. That being said, there's no reason to remove ntpdate. You can just disable it using bum, as previously mentioned.

BUM is available in universe

sudo apt-get install bum

lol

[emendelson]

Another easily reversible way to do this is

cd /etc/rcS.d
sudo mv S51ntpdate _S51ntpdate


If you ever want it back, just rename the file.

i can install and even run bum. but i must admit, i'm not able to enable the startup script ntpdate nor any other script :(

Guess what?
/etc/network/if-up.d/ntpdate

Can't they just leave the clock alone?
