(This may work on other versions of Linux, but I have only tested in Ubuntu GG)
WARNING! Although everything worked fine on my laptop, if something does happen to go wrong on your computer, it has nothing to do with me or CompuForums! use the following commands and your own risk!!


Okay,so to start of, install a cool little application called BootChart.
This will monitor everything that happens when booting your computer up.
It puts everything into a chart for you, so you can see what is taking
the most time to start.

----------------------------------------------------
Install BootChart
----------------------------------------------------


Next you ill have to reboot your computer.
Once rebooted, and you are logged in, navigate youself to:
/var/log/bootchart
In here will be a .png describing how long ach process took to boot up.



----------------------------------------------------
Ubuntu Hack
----------------------------------------------------

/etc/init.d/rc

And change the line
CONCURRENCY=none
to
CONCURRENCY=shell

----------------------------------------------------
Install a Boot Process Adjustment Tool:
----------------------------------------------------

Then boot it up using:
(To turn a device of, untick all the tick boxes within that row)

bluez-utiles
Since I do not use any bluetooth tools, I turned this of.
If you use any bluetooth tools on a regualr basis, I'd keep this on.

dns-clean
This is used to clean the DNS information when using a Dial-Up connection.
As I do not use Dial-Up, I turned this of. If you are using Dial-Up... Keep it on!

fetchmail
This is a mail reciving deamon. As I only use Hotmail, I turned this off.

hplip
HP printing and Image subsystem. As I do not ahve any printers ever connected to my
laptop,I turned this off.

mdamd-raid
If you do not use any RAID devices, there is no need for this tool to be turned on.

mdamd
A RAID management tool. Again, I do not use any RAID devices, so I turned this off.

PPP
PPP-DNS
Both of these are useless to me, as I do not use Dial-Up.

----------------------------------------------------

Now reboot your computer again.
Once rebooted, and your logged in again, navigate yourself to
/var/log/bootchart

Notice the boot time diffrence?





If you have any other methords of decreasing the boot time, then please do tell!

Great post. I'll have to do this because my Ubuntu does boot a little slow. It is not horrible slow because I have a lot of RAM and a powerful CPU.

Im scared to try this. Ive only recently re-installed ubuntu and lost most of my stuff so i think i'll save the hacking for a later day.
