Comment 74 for bug 1359689

I'm seeing this with the latest Ubuntu GNOME Xenial images. After completing a full disk encryption install the newly installed OS just boots to a blank, black screen. Then if you fiddle around with various key combinations (sometimes just repeatedly pressing esc) text will finally appear on the screen asking to "please unlock disk sda5_crypt". And if you hold your mouth just right you may be able to blindly enter the encryption password and boot with just the right keyboard combination. (pic attached)
