I note that, on the Acer V3-772G, Ubuntu shows the following, in
System -> Settings -> System -> Details -> Overview

"
Processor: Intel Core i7-4702MQ CPU A 2.20GHz x 8
Graphics: Intel Haswell Mobile
"

(In the window for that path in Ubuntu, it does not have a path
System -> Settings -> System -> Details -> Graphics)

so it apparently, is driving the inboard Intel graphics adaptor, and
not the nVIDIA GT750m graphics adaptor.

The Ubuntu information displayed, appears to not include the graphics driver.

I note that running lshw in Ubuntu 14.04 LTS, shows the NVIDIA graphics adaptor;
