Go to "System" -> Preferences -> StartUp Applications and turn off by unchecking needless services. For example, I unchecked Evolution Alarm Notifier, Gnome Login Sound, Gnome Splash screen, Remote Desktop (I dont use Remote Desktop), Update Notifier (Manual Update is better), User Folders Update, Visual Assistance(For people who has problems with eyes), any time you can turn on them.
Go "System" -> Administration -> Services. Here you dont need to turn off anything. Here you can turn off Bluetooth (if you dont have it), Apache and Sabma,
In Synaptic install "bum" package. After, go to "System" -> Administration -> "BootUp-Manager", and turn off what is needless. WARNING: DO NOT TURN OFF ANYTHING, JUST TURN OFF WHAT IS REALLY NEEDLESS.

Decrease Boot Time (speed) in Ubuntu 9.04 Part 1

Saturday, 9. May 2009, 15:17:52

ubuntu, geeking, desktop, linux

First off all, install "bootchart" package, from Synaptic package manager. This application is needed for comparing with current boot speed.

Now please restart your system ... After restarting you will find PNG file with boot time in "/var/log/bootchart" directory. This time is till loading GDM.

After rebooting, lets tweak our Ubuntu now.

1. Lets change boot screen.

Open Menu.lst

sudo gedit /boot/grub/menu.lst

Find and change the line with

kernel /boot/vmlinuz-2.6.28-12-generic root=UUID=619b888a-ccd8-40b8-a1dc-8ca721829b3f ro quiet splash

kernel /boot/vmlinuz-2.6.28-12-generic root=UUID=619b888a-ccd8-40b8-a1dc-8ca721829b3f ro

2. After Kernel loaded, system loads initial ramdisk, initrd. If you would extract this archive it will take about 25 mb, so we can re-build initrd. It is easy process.

Just open

sudo gedit /etc/initramfs-tools/initramfs.conf

Find line

MODULES=most

and change it to

MODULES=dep

Now rebuild it, with command

sudo update-initramfs -k all -u

Now it takes about 6-7 mb after extracting.

3. If your CPU has 2 or more cores ... you can do like this ...

Install "insserv" package from Synaptic.

Open

sudo gedit /etc/init.d/rc

Find line

CONCURRENCY=none

and change it to

CONCURRENCY=shell

Now reboot your system and see your result.
