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

and, as you have mentioned above, from

00:01.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] Mullins [Radeon APU A4-6000 with R2 Graphics]

"


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

"

The Advanced Micro Devices, Inc. [AMD/ATI] Mullins [Radeon APU A4-6000
with R2 Graphics] is under the Video category and is contained in the
certified systems below.

and, lists, as certified systems,

and

"
HP Compaq 15 Notebook PC Laptop

"


and the link that I have cited, for
http://www.ubuntu.com/certification/catalog/component/dmi/4365/dmi%3AAMDE2-6110APUwithAMDRadeonR2Graphics/

has

"
AMD processor AMD E2-6110 APU with AMD Radeon R2 Graphics Processor

"

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.
