[SOLVED] GPU Intel (Valley View) is working with lower capacity

Hi there, I have a trouble with my GPU Intel Card. It is supposed to work near 2 GB of capacity, but only shows 256 M in space. I've already builded the stack release 2015Q4 and doesn't fix this issue.
Here is my «lspci»

Is there a manner to adjust the gpu size via a config file?

These GPUs are built to manage the amount of RAM they use dynamically. As it seems, 256MB is the minimum that is always assigned to the GPU, this should increase when you run memory-heavy workloads on the GPU.

lspci is not always accurate in listing the memory of a video card either, because some memory is reserved elsewhere. I had a 1GB card being listed as 256MB.
