<p>For <strong><em>The display is blank</em></strong> & <strong><em>The display flickers</em></strong></p>
<p>I faced the same issue but now every thing works fine.</p>
<p>There are two solutions to this:</p>
<ol><li><p>Use NVIDIA driver version 364 from the Graphics drivers PPA (Best Option)</p>
<ul><li><code>sudo add-apt-repository ppa:graphics-drivers/ppa</code></li><li><code>sudo apt update && sudo apt install nvidia-364</code></li></ul></li><li><p>Use LightDM instead of GDM</p>
<ul><li><code>sudo apt-get install lightdm</code></li><li>choose <code>lightdm</code> as the default when prompted.</li></ul></li></ol>
<p><strong>NOTE</strong>
If that didn't work for you, install <code>intel-microcode</code> (if available) from the Additional Drivers app before installing the NVIDIA driver.</p>

<br>
Have an optimus laptop (intel-4600 and nvidia-GT860M) that I used to<br>
use for Steam Games, using intel as the boot GPU and nvidia (using<br>
primusrun) only for games. This took a long time to set up for 14.04,<br>
but eventually it was fine.<br>
<br>
I upgraded to (early version) of ubuntu 16.04 last November, and since<br>
then, have been running only on intel, because every time I tried to<br>
install nvidia<br>
drivers, I just get a black screen. Had been waiting for things to<br>
stablize after release, but it looks like things are still just<br>
massively broken.<br>
<br>
The black screen has an underscore at the top-left of the normal X<br>
(Ctrl-F7 or F8, not sure...) screen. Ctrl-F1-6 gives me a totally<br>
blank screen... so no tty access at all. I normally have an ssh<br>
server, but cannot ssh in when it is in this state either.<br>
<br>
If I boot with nomodeset, then I get to a login screen, I enter the<br>
password, and it just pops back to the login screen. And there are<br>
still no tty's... So booted off of a USB media and used a chroot<br>
environment to purge nvidia- drivers.<br>
<br>
I see recipes to get out of the black screen... but all they do is<br>
switch to nouveau drivers, which won't run games acceptably. I am<br>
looking to use the nvidia drivers to run games, but normally use<br>
intel, as I did with 14.04.<br>
<br>
Step 1: any ideas on how to install the nvidia driver so that I have<br>
a functioning system?<br>
