I think you should concentrate on the string in brackets,
which appears on

Now, you say that, but, Ubuntu 14.04 shows two different sets of
information, as shown in my preceding messages;


"



I note that, having just installed (and presently updating) Ubuntu
14.04LTS, on the Acer E5-521-238Q, the same graphics drive shows as
being used, as for Debian 7 on the Acer V3772G;

from System Settings -> Hardware -> Overview, I have

"
Processor: AMD E2-6110 APU with AMD Radeon R2 Graphics x4
Graphics: Gallium 0.4 on llvmpipe (LLVM 3.4, 128 bits)
"


"

and, as you have mentioned above, from

"

bret@bret-Aspire-E5-521:~$  lspci | grep -i vga

"
"


and

"
and, from the lshw output,

"

So, Ubuntu shows the CPU as being both
"AMD E2-6110 APU with AMD Radeon R2 Graphics x4"
and
" [AMD/ATI] Mullins [Radeon APU A4-6000 with R2 Graphics]"

unless, an AMD E2-6110 incorporates an AMD A4-6000 with R2 Graphics

?

But, the link that you sent, links to
http://www.ubuntu.com/certification/catalog/component/pci/1002%3A9852/

which has

and the link that I have cited, for

has

So, what I deduce from this, is that the only difference between what
you have posted, and, what I had previously posted, is that you have
referred to the video component
(" [AMD/ATI] Mullins [Radeon APU A4-6000 with R2 Graphics]")
of the CPU that I had specified;
("AMD E2-6110 APU with AMD Radeon R2 Graphics x4")

but, however it is interpreted, my deduction that both Debian 7 and
Ubuntu 14.04 LTS, appear to be lacking a(n adequate) driver for the
particular CPU (given that it involves and includes, as an integral
part, the " [AMD/ATI] Mullins [Radeon APU A4-6000 with R2 Graphics]"
graphics controller), appears to be reasonable and valid.

I note that none of the web page URL's that you and I have cited,
appear to link to, or, mention, a driver for the particular CPU or its
incorporated graphics controller, for either Debian or Ubuntu, Linux.
Have you tried "catalyst" for the AMD setup?? Under AMD Mobility Product Family your 6000 series is listed. 
http://support.amd.com/en-us/kb-articles/Pages/AMDCatalyst14-9LINReleaseNotes.aspx
Of course you would need the AMD driver and use that instead of the plain jane SVGA you are currently using. I use nvidia, but without the nvidia driver installed, I don't get the goodies love that I want, like multiple monitors (4) using multiple cards (2). When trouble shooting with a shotgun, sometimes a shot in the dark will hit something. :) Ric
