The pictureon the right (klick to enrange)  shows  how Ubunto boot process is going on my 5 years old Thinkpad T60. Bootchart utility does such charts automatically. If you interestiong how easy it it to enable such bootcharting read below.

Installing bootchart

See how to install bootchart logger on ubuntu, and other linux distributions.

Yo need bootchart and, pybootchartgui

apt-get install bootchart

apt-get install pybootchartgui  

That will automatically add bootchart logger to your grub configuration . Restart your machine and look for an image file in /var/log/bootchart directory.

Disabling bootchart

Someday you maybe wan't to disable bootchart again.

To disable it just throw it out of your GRUB configuration. On GRUB 2  (which is default on ubuntu since v. 9.10) you have to change file /etc/default/grub.

Change line
CMDLINELINUXDEFAULT="quiet splash bootchart=disable"
and then run:

sudo update-grub  

You done.

On GRUB 1 you have to edit /boot/grub/menu.lst.

Any comments?
