This is a real stupid question but I can't seem to find an answer. I completed the install of Ubuntu 804 on my mini 9 and am going through the learning curve of using linux. I am trying to make a directory, mkdir, and found that I need root access rights. A friend told me to login as root. Much to my suprise I don't know the root password. I was told that I stated it at the time of install. I tried every password I would have used and included nothing. I do not remember being asked a question for the root password. I have 3 installs of ubuntu on my machines and I now have found that I can not login as root on any of them because of this password issue. I don't know what this password would be. I am positive that I would have only used certain passwords for anything so I don't get it.
Any help would be appreciated and try not to laugh to hard.
