It's a fresh install, I am not upgrading from a previous version. As a matter of fact I installed Ubuntu 18.04 on two different computers and both behave the same way with the login screen: when I make a typo in the password, I can't login even if I type the correct password the next time. It just shows the wallpaper / background but nothing happens. By the way, the above bug-description is not mine: I just converted a question someone asked about a week ago to this bug report because I also have the same problem and nobody answered that question yet.
As for the package, sure if 18.04 uses gdm3 then it's gdm3. I was just following the Wiki you linked me which says that if it's the login screen then it's LightDM (https://wiki.ubuntu.com/Bugs/FindRightPackage#At_the_login_screen), so that documentation also needs an update because it's apparently out of date and contains false information. If you need me to attach logs, let me know. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1769416 Title: Can't login on 18.04 after entering wrong password Status in lightdm package in Ubuntu: Incomplete Bug description: Hello, so I just installed Ubuntu 18.04LTS on my computer ( HP Spectre x360 15 ), running in dual boot mode with windows 10, everything went well during the installation, the only problem I encountered is, if I type a wrong password and then I type the correct password, the desktop never loads... I waited like 20 minutes if anything would show up, but nothing, I can just see the cursor and the wallpaper nothing else, I had to manually turn off/on the computer multiple times, in order to see the boot manager again. If I enter the correct password at the first attempt, the desktop loads and everything works just fine.
