unable to login in non-graphic terminal (e.g. tty1)

[crysman]

I am unable to login in non-graphic terminal (e.g. tty1) ending with "Login incorrect" all the time because password prompt does not wait for user input.

Steps to reproduce:
1) switch to non-graphical terminal (tty1) with CTRL+ALT+F1
2) you see prompt for login ("login:")
3) type-in user login -> ENTER
4) you see password prompt ("password:")
5) try to type password... what you see is that it behaves as just as if you pressed ENTER before actually typing all the passwords characters
6) this repeats automatically 5 times and then screen is automatically reset with blank login prompt

I do not know since when this has occured, but it is VERY SERIOUS bug - if something happens in my X (tty7), I am unable to kill or manage it :/

What might be wrong?

[SOLVED]

I've found out what's the problem.

The issue is caused by SafeEyes (https://slgobinath.github.io/SafeEyes/) - after disabling them everything works as expected...

PS: the issue is not present any more. It had been for some two/three weeks, now it's gone... (no, I have not been using hibernation or suspend)
