[Bug 1389904] Re: With the recent update to xserver-xorg-video-intel, system boots to a black screen


The On-board i815 Graphics of an ASUS CUSL2 Motherboard boots to an
Entirely White Screen when Xubuntu 14.04.1/Mythbuntu 14.04.1 Systems are
booted.  Virtual Terminals are mostly White, with Characters which are
NOT legible.  Typing "Blindling" into a Virtual Terminal, I succeeded in
installing openssh-server/NX and synaptic so that I could Downgrade/Lock
xorg-video-intel 2:2.99.910-0ubuntu1.2 to xorg-video-intel
2:2.99.910-0ubuntu1.  Although the Login Screen and Xorg Screens are
working, the Virtual Terminals are still 'Garbled".

Within the Xorg.0.log the following was reported:

  With the recent update to xserver-xorg-video-intel, system boots to a
  black screen

Status in “xserver-xorg-video-intel” package in Ubuntu:

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

  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

  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.
