nVidia GTX 870M not detected

[m654321]

I have LL2.4 installed with Win8.1 in a UEFI enabled dual-boot set-up - working very well.

The laptop is an Asus G750JS, and comes with a dual GPU set-up: that is a default Intel GPU, and an NVidia GPU (Geforce GTX 870M), the latter kicking in when the graphics demand is high, e.g. when gaming. This system seems to work very well in Win8.1.

However, when I boot into LL2.4, the graphics are nothing special: the 'lspci' command in the terminal indeed reveals that only the Intel GPU is detected, not the NVidia one. 

My question is how can I:
(1) either silence the Intel GPU and use the NVidia one instead;
(2) or, better still, switch between either GPU whnever the need arises - I've seen online that some use software called bumblebee to do this but I have no experience in this deirection.

I've downloaded the lastest 64-bit linux driver (352.21) for the NVidia GPU from the NVidia website, but don't know how to install it properly.  I think I may have accidently deleted any existing NVidia drivers (331.67) that may have already been on the LL OS.

Any help much appreciated
Kind regards
Mike

Installing the nVidia driver the correct way is under the Video Drivers section of the Help Manual. You have Intel/nVidia, so you will be using the Optimus section instructions.

I followed your advice Jerry and typed in the following under NVidia Optimus in the Help Manual:

sudo apt-get update
sudo apt-get install nvidia-prime nvidia-331-updates nvidia-settings

After the 2nd line above I get this output...
Reading package lists... Done
Building dependency tree     
Reading state information... Done
Package nvidia is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'nvidia' has no installation candidate
E: Unable to locate package settings

So, the presence of the NVidia GPU is being ignored - what can I do now?

Can you try again, this time post a screenshot of the terminal window with the commands already having been run. Thank you.

Running the lspci command again, apparently shows NVidia being detected this time (see blue font below), though appears to be given an alternative labelling,
i.e. GK104M. My questions are:
1) How can I then run the laptop in NVidia rather than Intel graphics mode, given that Intel mode is the default one for this laptop?
2) How do I know if I am running in NVidia mode (or not)?

I have LinuxMint installed no issues, bumblebee/Optimus setup however it takes some time to get it properly working.
My hardware is- i7-4710HQ CPU, Nvidia 860m, 16GB DDR3, Win7 on a 128GB SSD, LinuxMint on 1TB HDD. I created another partition for LinuxLite and installed it last. EVERYTHING works! At install select "something else" on partitions. I didn't bother with UEFI, only grub.

Here are the guides i used to set it up, just know they were NOT written "specifically for LinuxLite" , I installed on LinuxMint.

There were more sites, but I was able to figure it out from these sites. The last one was more help to me.
Take your time, I had to reinstall 2 times because I was not patient.
For my Nvidia 860m I use the 349.16 driver. It gets warm but I run it on full graphics/Nvidia.

UPDATE
Asus GL551JM Boots up from usb or dvd -when i disabled intel-virtualization. After install it was enabled and works fine with virtual box.
I installed the latest driver listed in "hardware drivers" section, no issues.

OLDI havn't been able to get my Asus GL551JM to even boot LinuxLite, would you be so kind to post your BIOS settings?
Have you ever gotten "machine error" when booting LinuxLite ?

Thanks. The last of those links helped me with my machine (card GTX 850M, i5 ) after I installed the latest kernel 4.1.1-linuxlite.

Before that I was using the Intel card only as the nvidia wasn't found..
