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.

  • Just tried this , and I still have a few questions : 1)Could you explain why the 361 version is used ?2) The Displays window shows "Built-in" display , shouldn't I see something like Nvidia GeForce ? – Natasha Aug 29 '16 at 18:06
  • The 361 driver is in Ubuntu repositories. 2) Display is not "video dapter" it is display ;-). It is built in your laptop. What is wrong?

  • See this for some more information. – Pilot6 Aug 29 '16 at 18:10
  • what is the difference for example between nvidia-364 and nvidia-361? When I was choosing what to install previously I looked up the nvidia card on the official site and found the version 367 from there, so is there a reason for suggesting 361? I saw several answers that suggest different nvidia driver versions and I can't figure out how they are related to the actual hardware – Natasha Aug 29 '16 at 18:53
  • You have 364, 367 because you have added a 3rd party PPA. Ubuntu has 361. – Pilot6 Aug 29 '16 at 20:27
