Boots to Black Screen.

Hello. I just tried to install i3 in Ubuntu 16.04, but every time I boot up now, Ubuntu loads into a black screen. By using grub, I am able to access a su terminal, but I'm not to sure what the problem is. I run

i3 --moreversion 2>&- || i3 --version 

and the output is

Binary i3 version: 4.13 (2016-11-08) \copyright 2009 by Michael Stapelberg and contributors

When looking at the website, I notice that the website has another line with "Running" below this. i3 is installed in my /usr/bin/i3 folder. When running i3 reload, I get a line "ERROR: Could not get i3 IPC socket path. Any ideas?

Edit: When running

ps -A | grep i3

There is no output.

Edit 2: I was able to get it i3 working from my root recovery mode by first running

mount -o remount,rw /

to mount it as read write, then

xinit path/to/i3

to start i3, but this only starts it for root. I still can't get it to start at boot.

Edit Final: Turns out some commands are a little outdated from 12.04 to 16.04..... in my .xinitrc file I added

xinit i3

instead of

exec i3

And now it works. Woo. Issue closed.
