I recently installed Ubuntu 13.04 with dual boot to Win 7 without any issue. The login screen came up on Ubuntu with two accounts (Guest &amp; myname). I was able to login as guest but not through my name it said "Invalid password please try again". I have tried all possible passwords that i know off. Could anyone please suggest.  Thanks

I'm working on a Ubuntu system, and my client has completely forgotten his administrative password. He doesn't even remember entering one; however it is there.  I've tried the suggestions on the website, and I have been unsuccessful in deleting the password so that I can download applets required for running some files. Is there a solution?

What is the different between an Normal user account and the Admin account in Ubuntu?  You must always enter your password if you want do something. Can you give a Normal account  "limitations" to do not install or remove anything or to not open any program? Can you also "hide/deactive" the terminal and console for a normal user?

I had to reinstall recently. I installed normal Ubuntu 14.04. I then installed gnome/gnome shell/gdm. I then logged in my user to gnome. Since then I have been configuring my system.  Yesterday, unlock was working fine. Today, the automatic lock screen is not accepting my password as valid. It just takes the input like it's processing it, then takes me right back to the same password prompt. If I click the 'login as a new user' link, it takes me right back to the lock screen. Ctrl+Alt+F1, etc, does nothing.  I had to resort to a hard boot. I've tried this more then once. (first time was from automatic, idle time lock, second time was from my triggering the lock screen with the keyboard command).  I'm certain I have my password right, as I am able to get logged in after the cold boot.

I've installed Ubuntu, but when it is loading it gives following error:  mount:can't read proc/mounts. Can't fount such file or directory   However, OS continues loading but when I try to enter system using my login/password, which I entered during installation, it fails to login.  Does someone know what is problem here? I've tried reinstall ubuntu several times, but problem still occurs.  Medium from I installed: Windows 7. Installed Ubuntu with wubi, where I chose separate disk G(NTFS file format), set installation size: 18GB, chose Ubuntu in dropdownlist, language English(GB) and set username and password.

I understand that Windows can allow multiple different user logins to the same machine at the same time, either via remote desktop program such as Citrix or other means.  My question is that, does Windows allows multiple same user login to the same machine at the same time? Let's say, I have an account with the user name John, and this John gives the account name and password to his niece, and now both of them want to log into the Windows machine at the same time and do different things-- via remote login.   Is this scenario possible?

I've recently installed Ubuntu 18.04 in a dual-boot configuration with Windows 10. I noticed today that, when trying to open system settings, Ubuntu seems to log me out to the lock screen. When I log back in, all previously-running applications are now closed. Very unsure what to do from here, any help much appreciated.

I've had a lot of problems lately and now I'm having problems logging in at the login screen. I'm giving up and just want to reset and start over. How can I "factory reset" Ubuntu, in this situation, or, for future reference, in general?

Today I installed Ubuntu 14.04 on my computer. I have dual monitor setup, and they work perfectly when I'm logged into the operating system. But every time I have to login in the login screen, the screens get reversed. And what I mean is that instead of moving the cursor on the main screen to the left to move on the secondary screen, I have to move it to the left side. After login it changes to normal.   Any suggestion would be helpful.  Graphics: NVidia GTX275. Latest drivers installed.

The problem can be reproduced as follows:   When I remove the password of an administrator account, "Log In without Password", I cannot use that account to authenticate. When I do something that requires authentication, I cannot use an admin without a password to authenticate. If I leave the password box blank without a password while choosing a non-password admin, authentication fails (in terminal or in GUI).   How to fix this problem?

Long story short, someone repaired my brother's computer and set a password on his account, now we can't get in and can't contact the person who set the password.  Is it possible to create a Windows XP user if I have access to the windows partition, from a linux partition or pendrive, for example TinyCore?  Thanks for any pointers!

How can I give a user one password for normal usage when logging in, and another password for system administration and sudo access? I want one user to have two passwords.

If I enter my password correct first time, I login as normal.  If I enter my password wrong, it says invalid password. If I attempt to enter the correct password now then the screen freezes and doesn't go to dock as normal. I must restart using a physical button or shutdown to get out. Login works normally after restart, assuming I get it right first time.  EDIT:  After entering a wrong password, if I click cancel and then go back to my user to login, it works fine.

I am trying to use the su command to run an application as another user  In this case I am trying to run irssi  blah@ubuntu: su - [username] irssi (enter password)  blah@ubuntu: (nothing happens)  blah@ubuntu: su - [username] -c irssi (nothing)   I run gksu and set same parameters and it works, and doesn't ask me for the user password. What is the issue? And how do I solve it?  I should note the user was created like this  adduser --system --disabled-login [username]   if it makes any difference....sigh.

I disabled all services in services using msconfig and restarted.  Now - my login details no longer work. I have no network access and the forgot my password option doesn't do anything.  I have restarted using shift+restart to try get into safe mode but this just brings me to the same logon page.  Does anybody know what caused this or how I can resolve the issue?
