Moved from Installing Gentoo to Other Things Gentoo.
Not about getting gentoo installed, so moved here.

When I installed kubuntu on my wife's laptop once, I must have mistyped the root password in the installer twice, because the root password never worked. Is it telling you it is the wrong password, is it giving you an error, or what?
The wheel group allows you to use the sudo command, and then you use your user password. It grants superuser access for that one command.
The su command switches you to the root user, and you stay logged in as the root user. You don't use your user password, but rather your root password.
However, if you have questions about sudo and the wheel group, this may also be helpful:

Ubuntu-based distros don't ask you for a root password, only for an user one. The root password is scrambled (the account is "locked" with "passwd -l"), so the only way to obtain root access is through sudo. If you want to enable the root accout you must do "sudo passwd root" and establish a password for it.

dumb question: have you logged out of whatever shell you are in after you added your user to the wheel group and then logged back in? on my machine, if I want a new group to be recognized I have to exit gnome totally and log back in. |

That was probably it then, and I was too tired to forget what I did when I installed it. I assumed it had asked me for a root password.
I actually loathe that the installer doesn't even ask me to pick packages, or even groups of packages. I'm not sure why everyone loves the *buntu installer. Users aren't complete and utter idiots. With Yast and other installers, if you have no clue, you can take the default packages, but at least ask people and give them a damned choice.
Sorry, rant mode off.

Yes, I have logged out of the shell. Its been long enough that I have restarted the computer and logged in many times.
I can use sudo command; however, I do not want to give sudo users all of the power of root.
The message I get tells me that I have entered the wrong password:
| Quote: | Password:
su: Authentication failure
Sorry. |
I know that my root passwd works because I can log in as root.
My output from " id; ls -l /bin/su" is:
| Quote: | uid=1000(jake) gid=1000(jake) groups=10(wheel),18(audio),19(cdrom),27(video),35(games),80(cdrw),85(usb),100(users),250(portage),1000(jake),1003(gdm),1005(plugdev),1006(admin)
-rwx--x--x 1 root root 31088 Sep 1 12:11 /bin/su
