This problem is still there in Lubuntu desktop, which means the desktop iso file with the graphical user interface.
The problem appears on desktop computers as well as on laptop computers, and I think it is caused by problems with plymouth (which displays nothing, no logo, no dots, (and no passphrase if disk encryption is selected). The problem is that the passphrase is not displayed, but it is still possible to type it and finish with the Enter key. That brings you to the login screen of the installed Lubuntu system. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1359689 Title: cryptsetup password prompt not shown Status in linux package in Ubuntu: Triaged Status in linux source package in Utopic: Won't Fix Status in linux source package in Vivid: Triaged Status in plymouth package in Debian: Fix Released Bug description: Currently in utopic the following happens when booting an encrypted setup: Press enter in grub, after a while screen freezes (or turns completely black) and stays like that.
