can't login after run su command
 
hello, I can't login after run "su -c 'vidalia'"(I was installing tor), after that I can't run anything in my desktop, "denied permision", and restart my computer, but can't login in, when i put my username and my password, a dialog box with a message, "startxfce4 not exist", but I login with the root user, and I made a new user, but have the same problem.
how can fix this problem?

I'd start by investigating just what the command 'vidalia' does.

sotitrox,
Ref the man page for the su command:

Code:
man su
NAME
su - change user ID or become superuser

SYNOPSIS
su [options] [username]

DESCRIPTION
The su command is used to become another user during a login session.
Invoked without a username, su defaults to becoming the superuser. The
optional argument - may be used to provide an environment similar to
what the user would expect had the user logged in directly.

Additional arguments may be provided after the username, in which case
they are supplied to the user's login shell. In particular, an argument
of -c will cause the next argument to be treated as a command by most
command interpreters. The command will be executed by the shell
specified in /etc/passwd for the target user.


Did your command "vidalia" finish? Were there errors? Maybe if you do the following command, as root, you can see
more error information in detail:
Code:
dmesg |tail

Can't you do a CNTL ALT F1 and get to a Terminal, and login to use the commands like: user, who, finger, and others to
see who is logged in etc..? CNTL ALT F7 will take you back to your GUI.

What is the URL of the guide, blog, or tutorial you were following?

Thanks.

LK

the problem is (I think) the file permissions, i don't know how to use tor, and when finish the install, I run vidalia, but I can't, because not permission to do that, and I run vidalia with super user privilegies, and ta-da, the normal user can't login or run anything, only the root can.

this is the web where I manually edited in my pc, http://slackbuilds.org/repository/14.0/network/tor/

his script requires a 'tor' user/group to exist before running.
The recommended UID/GID is 220. You can create these like so:
groupadd -g 220 tor
useradd -u 220 -g 220 -c "The Onion Router" -d /dev/null -s /bin/false tor
I do that, and then install vidalia, the interface of tor.

I solved, but i don't know if will be have another problem for that, but I login normally and i can run anything normally.

It was a permission problem, I found the answer in google https://bbs.archlinux.org/viewtopic....16939#p1116939.

only run:

Quote:
chmod 755 /usr/bin
solved my problem, :D, and never, never!!!! run vidalia as a root user :D
