Bootchart is a tool for performance analysis and visualization of the Linux boot process. Resource utilization and process information are collected during the boot process and are later rendered in a PNG, SVG or EPS encoded chart.

Bootchart provides a shell script to be run by the kernel in the init phase. The script will run in background and collect process information, CPU statistics and disk usage statistics from the /proc file system. The performance data are stored in memory and are written to disk once the boot process completes.

To install Bootchart fire up your terminal and run this command

sudo apt-get install bootchart

The bootchart result is saved as an image after every boot process of your system and the image are saved in /var/log/bootchart/

Go into that folder after rebooting your PC to see how was your system's booting performance. How many seconds it took to boot?

Mine take around 30 seconds to boot.

This app will help you to keep an eye on your Ubuntu's performances every now and then.

Enjoy!

Sometimes we need to open a Terminal in a hurry at a particular location and the easier way to do is to add a "Open in Terminal" option in the right-click menu.

For doing that we have to run this command in the terminal.

sudo apt-get install nautilus-open-terminal

Now whenever we right-click on or in the folder or on the desktop we will get the option "Open in Terminal" in the menu and we can open the terminal.

Restart Gnome for the changes to take effect.

I found a great video on youtube.com about installing Ubuntu along with Vista. It will be a dual boot where one can choose while booting the system wether he wants to go in Vista or Ubuntu. This video is created by a youtube user called CoverlessTech

This was the first time I did an upgrade from one version to another version of Ubuntu instead of doing a clean install. I did this so that I don't have to reinstall all the necessary softwares which I normally do after the clean install also I was having no intention to try the new Ext4 filesystem which Ubuntu 9.04 was having as an option since I heard it is not entirely stable and still have some bugs.

So I got the notification from the Update Manager about the availability of an upgrade to Ubuntu 9.04. Here is the Screenshot.

So I click on the upgrade button to do the upgrade and the upgrading process begins.

For some odd reason the downloading of the files from the Internet was very slow maybe because many users were upgrading at the same time. Anyways it took me nearly 12 hours to do the complete upgrade but I was patient since I started the upgrade process at night  around 8 o'clock and after a couple of hours I went to sleep and in the morning at 8 o'clock the process was almost complete. After the process I restarted the PC as I was instructed and as soon as I restarted the PC I got this error.

But this error was not getting in my way and I was able to explore and operate the new Ubuntu 9.04 without any problem at all. After doing a search for a while on google I found the way to eliminate this error. I run this command on the Terminal 

sudo aptitude reinstall xkb-data

And the error was gone.

Conclusion : The Upgrade was a great sucess on my PC and its been a couple of days now since I did the Upgrade and every thing is working as smooth as ever without any problems whatsoever.
