12.04.3 shipped with the Raring HWE Stack, and 12.04.4 shipped with the Saucy HWE Stack. It's all explained in that link
One warning though, I have NOT found a method for properly downgrading the HWE stacks! All attempts resulted in borkage so I'm just leaving my production machines on the original Precise kernel and X-stack.
I disabled Boot on Lan and D2D in BIOS but I think that was not the problem. What I did was a trick we used during Precise dev iso ... Install from Live Unity Session. That set the video driver correctly with the latest iso release 12.04.4 LTS. There is still a problem installing Broadcom wireless drivers using the jockey but I know how to search the fix out for that and install them from terminal. Bottom line .. nothing has changed in Ubiquity, it appears, for touchy machines although not all laptops or desktops behave this way.
I get tons of unmet dependency errors, all of which revolve around the xserver packages. For example (and this is just a snippet):Code:sudo apt-get install --install-recommends linux-generic-lts-saucy xserver-xorg-lts-saucy
When I try to add those packages by adding them to my apt-get install command, I get to the heart of the matter. Namely, those new packages conflict with the quantal packages which are currently installed. For example:Code:xserver-xorg-lts-saucy : Depends: xserver-xorg-core-lts-saucy (>= 2:1.11) but it is not going to be installed
Anyone have any insight to this...?Code:libgl1-mesa-dri-lts-raring : Conflicts: xorg-renamed-package-lts-quantal:i386
You'll find the answer there
'libgl1-mesa-glx-lts-*" packages MUST also be upgraded!
This thread needs to be closed because 12.04.4 has been released and there will be no new images built.
General discussion of, or questions about Precise should be posted here:
And, of course, bugs should be reported on Launchpad.
Which gave me this:Code:sudo apt-get install --install-recommends linux-generic-lts-raring xserver-xorg-lts-raring xserver-xorg-core-lts-raring libgl1-mesa-dri-lts-raring libglapi-mesa-lts-raring libgl1-mesa-glx-lts-raring xserver-xorg-video-all-lts-raring
I've got both libgl1-mesa-glx and libgl1-mesa-dri set to be installed, but they still conflict.Code:libgl1-mesa-dri-lts-raring : Conflicts: xorg-renamed-package-lts-quantal:i386 libgl1-mesa-glx-lts-quantal:i386 : Recommends: libgl1-mesa-dri-lts-quantal:i386 (>= 7.2) but it is not going to be installed
FWIW: The command on the wiki also fails with the same conflicts:
Code:sudo apt-get install --install-recommends linux-generic-lts-raring xserver-xorg-lts-raring libgl1-mesa-glx-lts-raring
So, the trick was to do this and make sure I got both x86_64 and x86 libraries:
Code:sudo apt-get install --install-recommends linux-generic-lts-raring xserver-xorg-lts-raring libgl1-mesa-glx-lts-raring libgl1-mesa-glx-lts-raring:i386

The first paragraph of the wiki says:
In an effort to support a wider variety of hardware on an existing LTS release, the 12.04.2 and newer point releases will ship with an updated kernel and X stack by default. These newer hardware enablement stacks will be comprised of the newer kernel and X stacks from 12.10 (Quantal), 13.04 (Raring), 13.10 (Saucy), and 14.04 (Trusty). These enablement stacks are only intended for use on x86 hardware at this time. Those running virtual or cloud images should not need these newer enablement stacks and are thus recommended to remain on the original Precise stack. To remain on the original Precise stack there are a few options:
