When installed within VirtualBox with Guest Additions the first login prompt is sized 800x600 the second login prompt has dynamic screen resolution so is full screen. With "auto-login" for the user enabled the first 800x600 login prompt is skipped.
So my guess is that the Guest Additions code is run after you get through the first login prompt. Other code might also be run that allows you to successfully login with a second try? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1966786 Title: login screen shown twice Status in gdm3 package in Ubuntu: Confirmed Status in gnome-shell package in Ubuntu: Confirmed Bug description: The login screen is shown twice and I have to supply the password twice.
