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

[Aere Greenway]

Lubuntu Users:

Beware of the latest system updates for 14.04.01.

In it was an update for the xserver-xorg-video-intel package.

Seeing that, I thought I should check out my Compac DeskPro (933 
megahertz) machine with (as I recall) an i915 (old Intel) graphics card, 
to see if they had fixed the 'ragged graphics' a.k.a. 'tearing'.

As it turned out, they had indeed 'fixed' it, rendering the lubuntu 
partition un-bootable (even when earlier kernels are selected).

It appears to boot normally, but at the point the login screen should 
appear, a blank black screen remains (for who knows how long - it stayed 
that way until I finally hit the power button, upon which it initiated 
shut-down.

If you have a Lubuntu 14.04 system with the old Intel graphics, applying 
system updates may destroy your system.

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:
   New

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.
