Ubuntu – Installing Ubuntu 16.04 drivers for Nvidia Geforce 820M

16.04aptdriversgraphicsnvidia

I have a Lenovo Z50-70 laptop, which has Intel Integrated Graphics and an Nvidia Geforce 820M; however, since I installed Ubuntu 16.04, it has not been using the graphics card. I have tried uninstalling everything Nvidia-related and reinstalling nvidia-375, which then declares that it depends on libc6-i386, which then returns

The following packages have unmet dependencies.
 libc6-i386 : Depends: libc6 (= 2.23-0ubuntu3) but 2.23-0ubuntu5 is to be installed
E: Unable to correct problems, you have held broken packages.

When I try to install libc6, I get libc6 is already the newest version (2.23-0ubuntu5).

How do I install these, or is there another way to make my graphics card work?

In terms of other commands:

lspci -vnn | grep 3D -A 12 returns:

03:00.0 3D controller [0302]: NVIDIA Corporation GF117M [GeForce 610M/710M/810M/820M / GT 620M/625M/630M/720M] [10de:1140] (rev a1)

Best Answer

The Nvidia adapter will be seen if you instead of grep VGA will use grep 3D.
nvidia-340 is wrong for this adapter. Install nvidia-375.

You have only main and universe repos connected. Go to System Settings -> Software & Updates and enable all other repos, especially restricted. xenial-updates is not connected either. You need to enable it as well.

You may need to update the system before you install the driver.

Ubuntu – Ubuntu 16.04: nvidia drivers for GeForce GTX 960M

This file was modified by the Community with no fresh time stamps after May 7 2016, but there should be one for Sep 16 2016 because it showed up on the active list.

The answer above sudo apt-add-repository ppa:graphics-drivers/ppa today results with:

 Fresh drivers from upstream, currently shipping Nvidia.

## Current Status

We currently recommend: `nvidia-367`, Nvidia's current long lived branch.
For GeForce 8 and 9 series GPUs use `nvidia-340`
For GeForce 6 and 7 series GPUs use `nvidia-304`

nvidia-370 is the current BETA release!

## What we're working on right now:

- Normal driver updates
- Investigating how to bring this goodness to distro on a cadence.

## WARNINGS:

This PPA is currently in testing, you should be experienced with packaging before you dive in here. Give us a few days to sort out the kinks.

Volunteers welcome! See also: https://github.com/mamarley/nvidia-graphics-drivers/

### How you can help:

## Install PTS and benchmark your gear:

    sudo apt-get install phoronix-test-suite

Run the benchmark:

    phoronix-test-suite default-benchmark openarena xonotic tesseract gputest unigine-valley

and then say yes when it asks you to submit your results to openbechmarking.org. Then grab a cup of coffee, it takes a bit for the benchmarks to run. Depending on the version of Ubuntu you're using it might preferable for you to grabs PTS from upstream directly: http://www.phoronix-test-suite.com/?k=downloads

## Share your results with the community:

Post a link to your results (or any other feedback to): https://launchpad.net/~graphics-drivers-testers

Remember to rerun and resubmit the benchmarks after driver upgrades, this will allow us to gather a bunch of data on performance that we can share with everybody.

If you run into old documentation referring to other PPAs, you can help us by consolidating references to this PPA.

If someone wants to go ahead and start prototyping on `software-properties-gtk` on what the GUI should look like, please start hacking!

Be advised there are instructions on Nvidia site about disadvantages of upgrading Debian (which Ubuntu is based on) versus clean install.

Also be advised Nvidia website might have special instructions for Haswell, however their current drivers use the same one from my lowly GT650M up to OP's GT760M but there can be all kinds of recommended changes in other areas of the system based on Intel CPU and/or systemd or Debian.

Also there are special circumstances like the OP where Integrated Graphics and Discrete Graphics aka "Hybrid Graphics" are built into the Motherboard.

The Nvidia website does talk about black screens that are common questions in A.U. (Ask Ubuntu) so it's a worthwhile visit for most reading the OP's question.
