Well honestly we're not sure which kernel driver is to blame, but I
think we're safe if it's not Intel. There are ways to roll it back if
worse comes to worst.
By the way, I'm using the i915 driver with no problems.

The problem I reported where Lubuntu 14.10 and ubuntuMATE 1410 won't
boot on my Dell DX-1100 machine is a different problem from this one.
On some release later than release 12.04, the Intel graphics on this
machine performed poorly (jagged graphics gradients, a.k.a. tearing),
and even the Java Web-Start (IcedTea) logo window failed to work on 14.04.
Because of this, I took steps to use a different graphics card (a NVIDIA
geForce 6200), in place of the Intel graphics that appeared to have been
abandoned by Linux. Where this machine has no AGP port, I used a PCI
version of the NVIDIA card. To make it work, I had to set the BIOS to
do "AUTO" graphics card selection, rather than using the on-board
(Intel) graphics.
That worked, and I have been using it for some time. However, that
particular machine I have been using for my 12.04 LTS system testing, so
I stopped testing newer systems on it.
In collecting more information regarding this problem, I discovered that
even the Lubuntu 14.04 live CD system would not boot on this machine,
which was a big surprise, since I thought this was a problem with 14.10.
In experimenting with this machine, using different system levels, I
discovered that if I used the Intel graphics card (setting the BIOS to
use the 'onboard' graphics), the 14.10 live USB systems would not only
boot, but that the problems with the Intel graphics have been
corrected! I tried this with both Lubuntu 14.10 and ubuntuMATE 14.10,
both of which worked with no problems (as long as I didn't try to use
the NVIDIA PCI graphics card).
That was indeed a very pleasant surprise, for which I would like to
thank the developers profusely! The intel graphics has not been
abandoned, but is now supported, and has been fixed! So I can take out
the NVIDIA card, and everything will now be fine (well, I had a bit of a
struggle getting my Windows partition to go back to using the Intel
graphics, but I succeeded).
I still have the problem of the Lubuntu 14.10 live system (and
ubuntuMATE as well) not booting on my Compac Deskpro 933 megahertz
machine, which only has its very old Intel graphics). That is the
problem headline where Lubuntu 14.10 boots to a black (blank) screen.
But that is a different problem as well.
The problem described happening on the Dell DX-1100 machine, is actually
a problem where if you boot the Live-DVD 14.10 system (both Lubuntu and
ubuntuMATE), using a PCI (not AGP) NVIDIA card, with the BIOS graphics
selection set to 'AUTO', it apparently goes ahead and uses the onboard
(Intel) graphics card (which has no monitor connected to it), and
ignores the NVIDIA PCI graphics card (which the monitor is connected-to).
It would be nice if this would work (since the NVIDIA has better
resolution), but I can work-around the problem by just using the Intel
graphics card.
