I was trying to install xserver-xorg-video-dummy and said I needed to install xserver-xorg-core (which I assumed was already installed). So i typed
sudo apt-get install -y xserver-xorg-core
and rebooted and had some mouse problems and could've log in through the GUI. So I went into console and typed
sudo apt-get purge -y xserver-xorg-core
and then after reboot I realized I messed up and couldn't do anything on the computer anymore. Thankfully, I have another Linux OS to operate on (and recovery for my original Linux Distro). Is there a solution through the console, or do I have to reinstall? The Distro is a spin off of Ubuntu 14.04
