[ubuntu] Log on screen reverts back to log on screen after entering password

linux-howto

http://ubuntuforums.org – Ok..I'll explain what I did wrong, and then what I did to fix, which led me to my current dilemma. I thought I was going to be a smartypants and change my password to something really easy. Well, I goofed it up. When I tried to log on, I couldn't. So I accessed the root shell to change password, but encountered " change password authentication token manipulation error". I was able to get around that with "mount -o remount,rw /", and successfully changed the password. Now, the problem: When I enter the password on the log on screen, the screen goes black for a second, (Hardware)

Hey all, I recently changed my google account password. I am trying to log into google on my phone, however when I enter the new password, it keeps telling me "You have entered the wrong password or your account has changed.

I thought changing the password with 'encfsctl passwd path/to/encrypted' would change all filenames. But it didn't work. Any ideas why?

I got this, so the password was changed correctly:

Enter current Encfs password EncFS Password: Enter new Encfs password New Encfs Password: Verify Encfs Password: Volume Key successfully updated.

Hi

This question is usually responded to with "Liveuser does not need a password".

Well believe it or not in some configuration it is not possible to go passed the login screen of Fedora 11 or 12 KDE.

If you just hit enter which should work, it goes black with a blue flasy thing and then back to the login screen.

I have been using Ubuntu 12.04 for a few months now, but have now come across a problem that I can't get past.

I am stuck at the log on screen: I enter my password but a black screen flashes up and the log on prompt reappears.

I tried using the terminal and I actually have managed to login- but not using the main log on screen. I can't get my desktop active as the log on prompt is there.

I am kind of new to android phone. I am not sure how to do this.

I have an ActiveSync account and the Active server requires a password. So I have to enter a password in order to enter the phone.

I saw many locker screen apps in Google Play and it appears that they are not for password screen.

While studying "Learning the Shell" As I try terminal entries, I GET 'Permission Denied". Then I try "su" to become the root user. When I use the password that I entered as I installed Ubuntu 11.04, I get Authentication failure.
