Hi dear Ubuntu members,
A few weeks ago I set passwordless login, now I noticed that I can not revert it on Control Center-> Users and Groups. When I untick "don't ask password on login", nothing happens. When I run it as root "users-admin" it freezes. I think I can not have elevated privileges, or I messed up with settings. I tried to run Ubuntu-Tweak, when I enter login settings I can not unlock it.
I found a similar bug
But no fix posted.
I trust you Ubuntu gurus.
Please don't ignore my message.
