How to reset forgotten password in Ubuntu

If you forget your password in Ubuntu, you can simply set a new one:

• Reboot into recovery mode
• In the recovery menu choose "boot"
• Type "passwd <YOUR_LOGIN>"
• Type the new password (it will look like you were not typing) and press enter
• Retype (the same as above) and press enter
• Type "exit" and press enter: you'll go back to the recovery menu
• Select "resume normal boot"
• If the system restarts in console mode type "startx" after having logged in.

That's all, simple and fast! ;)

Ubuntu - No password resuming from suspend/hibernate (and viceversa)

Hate inserting password when resuming from suspend/hibernate on your home pc?

2. type gconf-editor and press Enter

4. customize the options by selecting/deselecting

Ubuntu - Enter password for keyring ‘Default’ to unlock

If this window (or a similar one) appeared while launching an application, here is what you've got to do:

Enter password for keyring ‘Default’ to unlock

An application wants access to the keyring ‘Default’, but it is locked

• FOR LINUX MINT & maybe recent Ubuntu (please let me know)

     0.   -->

1. In the menu, search for Passwords and keys; open it
2. In the "Passwords" tab you should have a folder Passwords:login
3. Right-click on it and select "Change password"
4. Insert your password in "Old password" and leave blank "Password" and "Confirm"

IMPORTANT NOTE: A security-information window will appear, but you can ignore it: your login password won't change, so your computer is still protected.. Maybe other users, once computer is logged in, can access those applications wich require a keyring password, but I think that if you leave someone your pc logged in, you trust them, don't you?

• FOR UBUNTU version 11.04 (and others? please let me know, also if it is correct)

   "An application wants access to the keyring 'Default', but it's locked."
   (thanks to a reader for his/her comment)

1. In the menu, under Applications search for Passwords and Encryption Keys
2. Right-click on Default-user, and then "delete"
3. Right-click on Login-user, and then "set as default"
4. The above NOTE is valid here too.

• FOR UBUNTU versions up to 10.10 with GNOME instead of UNITY

1. Go to  Applications –> Accessories –> Passwords and Encryption Keys
2. If in the "Passwords" tab you see "Passwords: default" select it, then  Edit -> Remove
3. File –> New –> Password Keyring
4. Insert 'Default' as name, and a password (not necessarely the login one)
5. Now you'll be asked the previously set password every time you log out; to avoid this you can leave the password blank.
6. The above NOTE is valid here too.
