For the past week or two, I've noticed my login process to be slightly different than normal. This made me wonder if there is a security issue I should worry about. So I started searching here, but could not find a clear answer.

I see many questions about being caught in a "login loop" but that is not what is happening to me (at least I do not think so).

When I startup my laptop running 18.04 (encrypted boot drive, up to date OS) I have to enter my decryption password. This is as it has always been. Then, I am greeted with the normal login screen. I enter my password and it looks like it was accepted (no bad password message, the screen is all purple momentarily but I can still see the mouse cursor, but I cannot move it) and before the desktop background (or any desktop icons) shows, I am returned to the normal login screen. There is still no message to indicate that my password was wrong. I enter the password, again, and it starts as usual.

What is so strange to me is that this is always a double login. That is, it never prompts me only once and it never prompts me more than twice.

I looked for the ~/.xsession-errors file but I do not seem to have it.

I've used this laptop for a year with 16.04 and I installed 18.04 just after it was released and there have been no hardware changes.

Any ideas?

  • Do these two login screen look identical? Could you add photos of them to your question if they're not? – pomsky Oct 12 at 4:39
  • @pomsky They are identical and look just like they always have. – John Oct 12 at 4:45
  • What's the output of apt-cache policy gnome-screensaver | grep Installed in Terminal? – pomsky Oct 12 at 4:47
  • @pomsky "Installed: (none)" – John Oct 12 at 5:18
  • Okay, so it seems this is not a duplicate of this. – pomsky Oct 12 at 5:24
