Notes

I followed the guide for Acer Aspire V7-482PG-9882 for most of the things mentioned there, but unfortunately this specific model doesn't work exactly as v7-482pg-9884. I want to mention that something I struggled so much is the graphics part. Now briefly I'm going to explain some important point:

- The other guide mentions to use the kernel boot options with “nomodeset”, but this enables for Intel drivers to not work properly once the desktop is on. And that means that OpenGL is going to be rendered as software rastering and not with hardware acceleration. Also means that it won't be possible to output VGA to an external monitor.
Use this boot options:
“quiet splash i915.i915_enable_rc6=1 acpi_osi=Linux acpi_backlight=vendor video=1920×1080-24@60”
It can be edited directly in /etc/default/grub changing GRUB_CMDLINE_LINUX_DEFAULT, saving and applying sudo update-grub

This will assure that Intel drivers are loaded before going to the desktop, a nice splash screen will show, and once inside desktop, Intel drivers can be updated normally. This will give the capability to use OpenGL properly and that VGA output can work normally.

The NVIDIA card is working the same way as Acer Aspire V7-482PG-9882 where is recommended to install kernel 3.12. Keep in mind that with this kernel there is a bug that prevent the laptop to completely shut down after exiting Ubuntu/Kubuntu (you manually need to press the physical button). Kernel 3.13 fixes this (tested), but unfortunately until this moment it is incompatible with NVIDIA drivers 331.38, giving a DMKS module error. Meaning that bumblebee/primus won't run. There is a patch available, but I haven't tested. So, in my case I preferred to live with the power down bug, sticking with kernel 3.12, than not be able to use the NVIDIA card.
