i created a user now i am only getting the cursor when trying to access from 5902port.

I'm not sure what exactly is the problem. Can you elaborate?

Note you can always change the login behavior by running the setup script. Also creating a new user should not affect the connection to the server.

yes, now I able to log in as a standard user( autobuild) .
Now i am getting 2 problems
1. I am not able to unlock any user, Ubuntu and autobuild both when i m logged as Ubuntu.
2.When i try to switch to the ubuntu or any different user i m not able to switch the user cause i don't get the option to choose another user.

Below i have attached the screenshots for both the problem.

You can switch account by clicking on the "gear" icon on the top-right corner.

However, it is known that "switching user" is not working in general. You have a better experience to just log out and log in again.

You can also customize the login behavior by running the AMI setup tool from the desktop.

Even i tried log out and log in again and again it prompts me the user ->autobuild only , no ubuntu user. The main problem is after i log in into one user i am not able to switch to the other user cause i dont get the opetion to choose another user, same thing i have uploaded in the screenshot

Please do not do "login"/"switch user" sequence. Instead, please do "login"/"logout"/"login as another user" sequence. This is more reliable.

Also make sure set up password when you create a new user so that the new user account is enabled. Please google "ubuntu add new users" for more tutorials.

Here is a picture of what it should look like when you log out or when you next time boot up.
