I installed Ubuntu 16.04 and the notebook overheats after a few minutes of light use. Previously I had Ubuntu 14.04.2 and I somehow solved the problem. I tried all the thing I could think of (remember from the 14.04 install) for this updated version of Ubuntu but still no improvement.

Here's what I tried:

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 540M] (rev a1)

I installed the nvidia 367.44 driver and set the profile to intel (power saving mode).

sudo apt-get install tlp tlp-rdw
sudo apt-get install indicator-cpufreq
sudo apt-get install thermald

EDIT:

lspci -k | grep -EA2 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
    Subsystem: Acer Incorporated [ALI] 2nd Generation Core Processor Family Integrated Graphics Controller
    Kernel driver in use: i915

01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 540M] (rev a1)
    Subsystem: Acer Incorporated [ALI] GF108M [GeForce GT 540M]
    Kernel driver in use: nouveau

The problem seems to be with the graphics drivers. I tried to install different versions and ended up with a black screen on startup. Solved it by doing the steps from Black screen after installing nvidia driver.

Now if I open All Settings -> Displays I have the "Built-in Display" and "Unknown display" , so there's still some problem with the drivers

You need to install Nvidia drivers.

Make sure that Secure Boot is disabled in BIOS.

Run in terminal

sudo apt install nvidia-361 nvidia-prime

and reboot.

For better powersaving state you can switch to the Intel adapter by

sudo prime-select intel

log off and log on to apply.

Pilot6 instructions are good.

You should also install Bumblebee to reduce overheating.

sudo apt-get install --no-install-recommends bumblebee

There is more information here

https://wiki.ubuntu.com/Bumblebee#Installation

You should also consider checking if your machine supports Intel P-State
