Hi everyone,
I'm a newbie and need some help.
I changed permissions to my home dir and some more dirs and now i CANNOT log in.When I start the Recovery mode it asks me for root login but don't know the password.I tried with my user's password but it says "login incorrect (or so)"
I know that I need to chown 644 my home dir but i can't login.
Plese help

Is it possible to log on as user and "sudo" to do whatever you need?

NO.
When I try to logon with my user = "Permission denied".
With 2 words: I have a working system without user permission to login.

I was able to login with root BUT it's a total mess with the permissions
I can't login with my user account (permission denied /bin/bash) and i can't start X server
Is there some way to restore the dafault permissions to my system ???

Exactly what files did you change permissions besides home?
For your /home folder
Code: Select all
sudo chown username: /home/username
(replace username with your username)

Yes, I changed the permissions to my home dir and now i see it BUT, I can't login.
I think besides my home dir is a TOTAL mess and even some devices (in /dev/...) cannot start because of that mess.
I screwed up things
I'll try to restore some permission to default but it's some kind of "Mission Impossible"
Next is ... reinstall (if i can't get defaults) !

What about creating a new user with root access?

I will do that, but there is many problems with files permissions
... like /dev/xxx/ (because they must be under 'tty' or something else ownership).For example when i start X under root account the mouse,printer,camera,audio and who know else DONT start.
I know there is many "system/internal" owners but I totally messed up things.
If there is some default permission settings it will be great, because I can't read about every specific ownership and search for this/these files to configure the whole system

Yea perhaps it would be easier just to back up any relevant data and reinstall
There may be a way to reset system ownership but I'm not aware of it.

That's what I'm thinking about too
However I Will try to chown most of the system dirs and files and if i can't login normally i will reinstall later.
Many thanx to you !!!
