 Posted: Tue Feb 17, 2015 6:44 am Post subject: Root login behaviour |
 |
|
when I log in as root I get the xfce desktop.
I only wanted this for my regular user session.
I'm using the xdm login.
How can I change it so that when I log in as root it goes to the command line?

Well, you shouldn't log into X with root. Ever.
Just switch to another terminal with Ctrl+Alt+Fx where x!=7 (that's the terminal which is usually occupied by X).
Also you can just open a graphical terminal with your normal user and in it swith to root with su. Your regular user just needs to be in the wheel group. |

Properly configured, sudo is an outstanding tool. It should eliminate 99.999% of your root login needs. su works also, so which you use depends on style.
That said switching a different TTY is an exellent work around. Personally, I prefer using no login manager and using a .zshrc file to automatically start X as my user when I log in from the command line. Root should be kept far away from anything flashy or complex.
Okay, I know this is a suggestion to avoid the problem rather than fix the problem, but sometimes the best solution to a problem is to avoid having it in the first place. As someone said, it makes more sense to unload a firearm than to shoot it into a bullet proof vest.

I guess that login managers which can be configured to disallow root login should have this in the default configuration.
The problem I have with sudo is that you must configure it properly. Especially since you don't need root's password to use it. And the default Ubuntu sudo config (everyone can do everything) makes me think that whoever thought it's smart should be slapped around for a while. |

OK guys, thanks for the good advice.
I can change to a tty with ctrl+alt+f2. (After some experimentation)
And get back to my regular user with ctrl+alt+f7.
I tried a sudo command from my regular user and got:
| Quote: | | User is not in the sudoers file. This incident will be reported. |
I guess from this that I have sudo installed.
Where can I read about setting up the sudoers file?
Any tips on doing this would be welcome.

Instead of working through complicated sudo setup you might consider not using sudo at all.
Then you don't even need to have sudo installed.
Try su -c "your command" and it will ask you for root login just only for your command. |

It's not hard to find  http://wiki.gentoo.org/wiki/Sudo
Also you can just use `su` instead `su -c <command>`. I find it the most convenient. |

catchpole ... as always 'man <command>', in your case 'man sudoers', though if you use 'visudo' you can read and edit /etc/sudoers ... which has some examples (note, always edit sudoers with 'visudo').

@charles17 ... while I don't generally recommend sudo (UOSCH) its not so complicated, its just people have a tendency to do ALL=(ALL) NOPASSWD: ALL for convenience.
best ... khay |

Thanks guys,
I'll try to setup sudo just to increase my knowledge and experience.
However if I want to do anything serious I'll use the tty. (Now that I know how to get in to it and return to the GUI)
