I just recently bought myself a Dell Inspiron 7559 and, of course, installed Ubuntu on my second SSD. Had to start up the installation disk with nomodeset as it wouldn't get past the loading screen. After installing the OS everything seemed to be running pretty decently until I tried installing the proprietary Nvidia drivers for my GTX 960M GPU.
I've reinstalled the OS 3 times after hosing the graphic settings to the point where X refuses to even load trying to fix the issue. Once I've installed the stable version of the proprietary driver in Settings -> Software & Updates -> Additional Drivers my laptop refuses to get past the login screen. It will appear as if it's loading, flash an fsck message on the screen for a fraction of a second, and then go right back to the login screen ad infinitum….
To cap things off, when the laptop 'is' working and isn't using the proprietary drivers the screen won't wake up from sleeping if I close and open the lid, though I'm thinking this issue also stems from the lack of a proper graphics driver.
How would I begin to resolve this issue?

I don't have enough rep to comment. I got Xubuntu 15.10 working on my Inspiron 15 7559 with functional suspend mode and the ability to switch between integrated and discrete graphics.
