If you have Ubuntu OS on your home computer, then you may not need the logon with password. If computer is always at home, this is not particularly necessary, and usually entering passwrod when system turns on or goes out from sleep mode is pretty boring. Below I’ll show you how to turn off password enterance on computer with Ubuntu when it turns on.Go to system setiings.
Then go to accounts.
Click unlock button and enter user password.
Then turn on autologon.
Now when you turn on the computer, you will not need to enter a password, but you will need to enter it if computer will go out from sleep mode. To turn it off too, go to the main system settings screen (All settings), and go to Brightness and lock settings.
There you should clear checkbox from require my password when waiking from suspend. Also if you want your desktop never locked principally (I mean if you want to go directly to the desktop bypassing the login/select user window), you have to turn off Lock setting.
After that, it may happen that sometimes the annoying keychain unlock window will pop up.
I already wrote about how to get rid of this in the article.
