Title:
Kernel 4.4x results in blackscreen - Intel Ivybridge
Status in linux package in Ubuntu:
Incomplete
Bug description:
When I install Ubuntu 16.04 on my computer the screen goes blank at
login. 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. If you require more, please ask.
