Description

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

Setup

Create multiple user accounts using the Users section of the Settings app.
You can set a password after you create new account or at first login: try both methods.
If you know how to type with different keyboard layouts, give each user a different keyboard layout, by logging in with each user and changing their keyboard layout in the Keyboard section of the Settings app.

Logout or reboot to show the login screen.
Verify that the login screen lists all user accounts, but not the root account. Each username should contain correct characters.
Log in with each listed account. Remember to select correct keyboard layout before you enter your password. Check that the keyboard layout used in the login screen remains the same after you login to the desktop.
Try to log in with an incorrect and a correct password typed when using wrong keyboard layout. Entering an incorrect password should show an error message.
Log in using the "Not listed?" option by specifying one of the accounts and its correct password.
Try to suspend (if available), power off, and restart from login screen.
- If you can't resume from suspend, it's usually not a bug of the login screen, but in hardware drivers, and not a failure of this test case (but you should still report it).
When logged in, use the Switch User menu item to switch between user accounts without logging out of them. You should be able to login with multiple accounts at the same time and switch between them.
Back at the login screen, use the controls in the top bar - keyboard layout, volume, power, etc and see whether they work correctly.
- Note that the keyboard menu will only show if you have multiple system-wide keyboard layouts configured.
