I can blindly login and it boots but I cannot use the display (external monitor through HDMI). I've looked online for an answer to this issue but could not find a solution. However, many people report this issue in forums with the 4.4x kernel. On my main computer, I upgraded from 14.04 to 16.04.1. On this computer I was able to switch back to the 3.13 kernel which *does work*. On the same computer, if I use a 16.04 live CD, it does the same thing. The screen goes blank. UEFI may be part of the issue as well. I have it disabled in bios (set to legacy mode) but when I first boot, it seems to go into UEFI mode first and then, after rebooting with <ctrl><alt><delete> it shows me the list of kernels. I can select the kernel from there but if I use a 4.4x kernel, it blanks out at encryption passphrase screen. There are also people with similar issues on AskUbuntu. Here's some basic HW info.
