When Ubuntu and/or Kubuntu are initially installed, a single user account was created. It is possible to create additional user logins on your system.
There is more than one way to add a user, however this wiki page will briefly discuss the easiest and most common ways. The two ways shown are:
- Command-line -
Graphical is the easiest solution, while the command-line offers the possibilities of multiple tasks at one time.
Location: System > Administration > Users and Groups NOTE: In the default installation of Ubuntu 9.10 'Karmic Koala', the + Add User button will be grayed out, and a Click to make changes button with a picture of keys will be an the bottom of the window. Click that and enter the sudo password to make the + Add User button active. Press + Add User, this will open up the User Account Editor. The minimum requirements are Username and password. For the Username, do not use spaces, and do use ASCII characters. On the User privileges tab, add privileges that the new user will have access to, such as use audio devices.
Location: Kmenu > System Settings > Users & Groups Press Administrator Mode, this will pop up a password box. Enter your password. Press New..., this will open up the User Account - KDE Control Module. The minimum requirements are Username and password. For the Username, do not use spaces, and do use ASCII characters. On the Secondary Groups area, press Select..., and add priviledges that the new user will have access to.
