Ubuntu - NVIDIA graphic card driver - stop X server

Are you trying to install a NVIDIA graphic card and you are asked to "Stop the X server"? Here is the solution:


type sudo apt-get install nvidia-current in terminal, or:
  1. make sure that the .run driver file is in a directory which path does not contain spaces (example: /home/file.run is ok, /home/my folder/file.run is bad)
  2. read all the following steps before following the instuctions and write them down on a piece of paper: you won't be able to use the computer in graphic mode while installing!
  3. Press CTRL+ALT+F1 and login with your username and password
  4. type sudo service gdm stop and insert your password for root privileges
  5. type sudo sh <filepath> where <filepath> is the directory path similar to the example in point 1
  6. follow the instructions on screen
  7. when complete type sudo service gdm start
  8. press CTRL+ALT+F7 to go back to graphic mode.
your graphic card should now work. =)

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.
