Hinto,
I appreciate the suggestions, but for some unknown reason they aren't working like I would have expected on my pc. Note that it gave me the authentication failure, but gave me a root login prompt anyway in this case. If I was to just try su, it would not have given me the root login prompt.
bobc@dv9000a:~$ sudo su
[sudo] password for bobc:
su: Authentication failure
(Ignored)
root@dv9000a:/home/bobc#
It did not allow me to change the password, from the looks of it, perhaps because I tried to use the same password again
root@dv9000a:/home/bobc# passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: Authentication token manipulation error
passwd: password unchanged
root@dv9000a:/home/bobc#
I get that same authentication failure from sux when I installed it and tried using it
bobc@dv9000a:~$ sux
Password:
su: Authentication failure
bobc@dv9000a:~$
I am ok now. I do appreciate the suggestions because I have almost no experience with ubuntu methodologies, and am floundering in those areas, just trying to accomplish basic tasks to get up and running.
I am now using sudo roxterm from a terminal prompt and able to accomplish those needed tasks. So I will mark this thread solved.
