After close to a year of running as root, yes I know most of the reasons not to, I've finally made a regular user. The problem is I can't su. I'm a member of the wheel group which seemed to be the only thing my searches turned up that might be a problem. I tried changing roots password and even deleting it, but I still couldn't get privileges.

Why would you run as root all the time? Damn, it's not windows where almost everything requiers root privileges. I honestly don't understand.

BTW Unfortunately, I can't help you....

Did you log out and log in again after putting yourself in wheel?

I ran as root because I'm lazy and by the time I knew better, I started running gentoo as a complete noob, I was having issues with xorg on non-privileged users so I just kept pushing off fixing it.

The user has been wheel since he was created and yes the computer has been restarted several times with that being the case.

xail,

Edit your /etc/sudoers file to allow wheel members to su.
By default, its full of commented examples

NeddySeagoon,
Thanks, I installed sudo, as I didn't have a /etc/sudoers file. I can sudo now, hurray.

I would still like to get su working if for no other reason then to figure out what was wrong, if you have any ideas. I realize that sudo is safer and usually considered a better choice then su.

If needed, see also Table of Contents :arrow: SA: System Administration :arrow: SA2: Why can't I su to root? (in the FAQs forum) for more possible causes.

timeBandit,
Thanks for the link. It was a permission error.

You're welcome.
Moved from Other Things Gentoo to Duplicate Threads, since the cause wasn't something new &/or exotic.

I don't know what I did. But I was sshed into one of my servers via my gentoo work station and now
I can not get root priviledge using $su -.

I've checked the gnome gui to make sure my user is able to get admistrative permission adn that item is toggles on.

None of the users I have can get "#su -"

Any idea oh great ones?

Thanks,
cwc

Your user must belong to the wheel group to be able to "su -".
Check /etc/group.

This error sounds like the suid bit is no longer set on /bin/su.

If that's the case, you can add it back after logging in as root with:
Code:
# chmod u+s /bin/su
