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

to

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.

To be continued ....
