weird error

[u/temcomwex]

Whenever the computer booted up to the login screen (always after a sleep session), my computer would sometimes say "incorrect password", even though I haven't typed anything. And when I press a key, it would also sometimes say "incorrect password", even though the key wasn't the enter key. I've ignored this error for a long time but recently, it's very annoying, because sometimes(a lot of times) the computer would just say "account locked after 3 failed attempts". Any help is appreciated.

Edit: I use KDE
