Running Lubuntu 14.04.1 i386 desktop with an Intel 815 video chipset, I
confirm the same behavior with any version of xserver-xorg-video-intel
newer than 2:2.99.910-0ubuntu1, but in terms of a workaround, I used
Synaptic to force a downgrade, then I locked to that version, and so far
software updater seems to respect that.

My troubleshooting and repair involved temporarily installing an ATI
video card.  After I found this bug, I used the ATI-equipped
installation to get to the desktop and Synaptic, and when I removed the
ATI I found that though I could now boot to the desktop under the i815,
the Plymouth splash screen is broken (a white screen with some evenly
spaced thin full-height vertical black bars across it).  And so far I
have not been able to fix it.

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.
