xrandr: randr is missing after installing xorg

Question

I am attempting to run xrandr because online it says you need xrandr to run lwjgl. However, whenever I try running xrandr it gives me the following error:

RandR extension missing

I tried running the following script:

sudo apt-get install xorg
y

And it still doesn't work. As a website said to do, I edited a file, which strangely did not exist already, and put in the following:

Section "ServerLayout"
    Identifier "Layout0"
    screen 0 "Screen0" 0 0
    InputDevice "Keyboard0" "CoreKeyboard"
    InputDevice "Mouse0" "CorePointer"
    Option "Xinerama" "0"
EndSection

Section "Extensions"
    Option "Composite" "Enable"
    Option "RANDR" "Enable"
    Option "Xinerama" "Disable"
EndSection

Here is the file I use to run Xvfb:

[supervisord]
nodaemon=true
pidfile=/tmp/supervisord.pid
logfile=/tmp/supervisord.log

[program:xvfb]
command=/usr/bin/Xvfb :99 -screen 0 1280x864x16 -ac -pn -noreset +extension RANDR -extension XINERAMA

[program:x11vnc]
command=x11vnc -shared -rfbport 5900 -display :99 -forever

[program:novnc]
command=./desktop/noVNC/utils/launch.sh --vnc localhost:5900 --listen %(ENV_PORT)s

[program:openbox]
command=fluxbox
environment=DISPLAY=":99"

Anybody know how to fix this?

EDIT:

Updated to 14.04.5. Removed my xorg file. Uninstalled 7 packages, including plymouth, udev, couchdb, etc. Did this because of an annoying dialog 'hotplug support required'.
