Title:
Ubuntu turns monitor permanently off during boot
Sorry for the delay. The 4.0 based kernel can be downloaded from:
https://launchpad.net/ubuntu/+source/linux/4.0.0-4.7/+build/7636518
You will need to install both the linux-image and linux-image-extra .deb
packages.

Were you still wanting to test this new kernel?

This does appear to be an Ubuntu specific kernel. I'll build an Ubuntu
kernel based on 4.0 and post a link to it for testing.

Wasn't testing with 3.16 and 3.19 ubuntu patched kernels enough to disprove
the grub theory?

Can you see if the bug still happens when booting a Trusty kernel on the
Xenial system? This can be down by downloading the kernel from:
https://launchpad.net/~canonical-kernel-
team/+archive/ubuntu/ppa/+build/10184623
You will need to install both the linux-image and linux-image-extra .deb
As a clarification, the mainline boot behaviour is identical to the Ubuntu
kernel with $vt_handoff removed. I double checked that the option is
present in grub for all the tests. I guess this isn't surprising since that
option isn't part of mainline.

4.1.0-040100-generic works
4.4.14-040414-generic works
Didn't test others.
The boot sequence is different with the main line kernels. There is a black
screen period with a couple of messages (1-2s), then the console font load,
then it briefly switches to the splash, black screen flash back to
Would it be possible to test the upstream stable 4.0 and 4.1 kernels?
They can be downloaded from:
4.0: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-vivid/
4.1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.1-wily/
We can perform a kernel bisect once we identify the last good and first

Yes. I've done multiple reboot experiments now and have learned the bug
only happens about 80% of the
Does booting back into the Trusty kernel on the Xenial installed system
make the bug go away?
