Title: Black screen when booting Status in linux package in Ubuntu: Incomplete Bug description: I have just upgraded from 16.04 to 16.10. The installation has dm- crypt installed in the whole hard drive. If I try to boot up the computer with kernel 4.8.0-26, most of the time (probably 9 out of 10) the computer gives a black screen instead of prompting for the dm-crypt passphrase. I try to remove "quiet splash" from grub (I can see the grub boot menu every time) but this does not help. Even I am lucky when the system prompts me for passphrase and the computer comes up successfully, the screen goes completely black again if the screen turns off once I idle the computer for a few minutes. The computer is still running (I can login to the computer remotely), just the screen becomes unavailable no matter what key I press. I still have the old kernel 4.4.0-45 from 16.04 installed and this kernel allows me to boot up the computer every time. My computer is a HP Elitebook 745 G3 notebook with AMD PRO A10-8700B R6 APU. Please let me know if I need to provide other information.
