This is my experience when I replaced my old Gutsy with Intrepid.

When I use Linux, I always divide my hard disc into 3 partitions, System, Swap and /Home. It’s a good idea because next time you want to replace your OS, you will not lost all your /Home data.

For your Virtual Box, you will still have most all of your old configuration and the image file. When I did this upgrade, I still have my old virtual box setup and my OS image inside it.

I said not all because the ‘saved state‘ you can’t get it back. You have to press the ‘Discard‘ before you can use it. But it’s ok, only take few seconds for an OS to reboot.

Below is the common error that I always have when I force my Firefox to close.

Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

You can’t fix it by log out from the system. You can only do 2 things, kill the Firefox process or restart your system. The second option will take a longer time, so let’s do the first one.

Open your Linux terminal (Applications>Accessories>Terminal) then type: ps ax | grep firefox.

You will see the PID number on the left side. PID is Program Identifier. The number can be different.

Have to have stop the process by kill the PID one by one.

Now, start your Firefox again. If you see the screen below mean the problem is fixed.

Another feature that I like from Virtual Box is ‘Full screen Mode‘. You can run another Operating System in Virtual Box as if that it is a real Operating system.
If it doesn’t work with your Virtual Box, probably you may have a problem with your display setting or card driver.

To change from ‘Normal Mode’ to ‘Full screen Mode’ in Virtual Box is very easy.
From main menu in Virtual Box, select File > Full Screen Mode.
