Public bug reported: After upgrading from Ubuntu 14.04.1 LTS to Ubuntu 14.04.2 LTS
Black screen during booting. Using: Ubuntu 14.04.2 LTS / Laptop ASUS K70AC - 500Gb Hard-disc (crypted) After started booting the screen turns to the Ubuntu colors for a second and then turns to solid black and nothing happens after that. I noticed that, when I quickly tuned off the power (battery -by removal- and mains) and then reinstalling and pressing the power button, the system showed me the GRUB choice with different Linux versions. Clicking the first (is newest) Linux version completed the booting. After having done this many times (no update for this bug so far), I clicked the F2 button (ASUS uses this key to get into the BIOS) while the screen was black, just to see what would happen. To my surprise my screen showed the following text (white font on black screen): Unlocking the disk /dev/disk/by-uuid/d9f96786-fec8-4889-b05e-96fcaffa6437 (sda5-crypt) Enter passphrase: After entering my passphrase Ubuntu completed the booting in the usual way!
