It appears that this affects a very specific chip. That being said, I
can't do much to help diagnose this. With that in mind, it would be
useful to find out exactly what conditions are required for this to
occur. Is it only that particular package? It should be tested across
different OS versions and flavors. Also, what other chips this may apply
to. It's clearly a regression of some kind because it did work, but I
can't push this upstream without adequate information.

Title:
With the recent update to xserver-xorg-video-intel, system boots to a
black screen
Status in “xserver-xorg-video-intel” package in Ubuntu:
Incomplete
Bug description:
The latest system updates for Lubuntu 14.04 includes an update to the
i915 display driver, which this machine uses.
After applying updates and rebooting, at the end of the boot process,
where normally the login screen appears, the screen remains blank
(with a black background color).
That change has rendered my Lubuntu 14.04 partition completely
unusable, even when booting earlier versions of the kernel.
Regardless the kernel level booted, the system now boots to a blank
screen.
Because of this, I had to report the error on my UbuntuStudio 14.04
partition, to which I have not yet applied updates. So the level of
the Intel i915 driver package in this error report is the version
prior to the updated version that (probably) caused the problem.
1. The release of ubuntu with the problem is Lubuntu 14.04.1, with a
kernel version ending in ".39".
2. The last working version of xserver-xorg-video-intel is
2:2.99.910-0ubuntu1 I can't boot by Lubuntu partition anymore to tell
you the version number that fails, but it is later than the indicated
version.
3. Prior to installing system updates, my Lubuntu 14.04.01 system
worked fine, and I was able to boot it and perform my suite of tests
(it's a test system). After applying updates, it boots to a blank
screen, and I cannot do anything with it. I expected the login screen
to appear, but it doesn't, and there is no error message.
4. After applying system updates I expected my system to reboot
normally, allowing me to login. Instead, a blank screen is displayed,
with no error message, and the login screen does not appear after many
minutes of waiting. If I hit the power button, it initiates shutdown.
Hitting several keyboard characters (or typing my password to the
blank screen) had no effect.
