I am using kubuntu 12.10.
My problem is when my kubuntu starts, in login screen it shows my name & a field for giving password (previously what i have choose for my account). But if at this stage, I hit enter or write anything & hit enter it gets log in!!! So strange! ( a huge security problem for me!) But in "sudo" it not working on any password, i have to give my selected password to access sudo!
how can my login problem be solved?!
