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 the external monitor does not work with either Debian 7 or Ubuntu 14.04LTS.

So, whilst the Ubuntu web site shows the CPU to be certified as
compatible  - at
http://www.ubuntu.com/certification/catalog/component/dmi/4365/dmi%3AAMDE2-6110APUwithAMDRadeonR2Graphics/

it appears to me, that both Debian 7 and Ubuntu 14.04 LTS, do not
really have an adequate driver for that CPU ("Processor: AMD E2-6110
APU with AMD Radeon R2 Graphics x4), as they both can not drive an
external monitor through it.
