In the mist of downloading and customizing my Ubuntu Linux, my password was changed. I'm not sure as to how it happed. I was reading a tutorial on customizing the look of Ubuntu and I got to a point in the tutorial where I needed to have root permission ""sudo nautilus". So i did what the article told me to and I was denied being able to run under root at that step. The only things that I had done prior to this was installed a few new themes, icons, and I was trying to do the splash. The root account in my Ubuntu is still disabled because I did not think to enable it so I don't know what else to do. I did try this one thing I found on the web where it told me to press esc at the Grub loader and edit the Kernel, but I did not get the root prompt when it rebooted. any advice would be greatly appreciated. I am running Ubuntu 8.04 on a gateway T1625 laptop dual booted with windows Vista home premium sp1
