Description

This test case focuses on graphical login screen, shown after boot, log out, and when user-switching.

Setup

Create multiple user accounts in "Usermenu" - "System Settings" - "User Accounts". Each account using different keyboard layout for username and password input. For example US QWERTY and FR AZERTY or Dvorak or your local variant.
You can switch between keyboard layouts using layout icon located in upper panel on the left side. For adding new layout select "Region and Language Settings" from icon's menu.
Try to use (special) characters not available on the other keyboard layout or located on different keys. Remember, usernames should contain only English characters, digits and allowed special characters ("." or "-" or "_"), passwords don't have this restriction.
You can set password after you create new account or at first login, try both methods.

Boot or logout to show login screen.
One by one try to login with each listed account. Remember to select correct keyboard layout before you enter your password.
Try to login with wrong password and correct password typed when using wrong keyboard layout.

The login manager should display all user accounts, but not the root account. Username should contain correct characters.
You should be able to log in with each configured user account using correct password. Check if keyboard layout is the same as you have selected in login screen, after you login to desktop.
Entering an incorrect password should return you to the accounts list, with a warning/explanation message.
