# System prerequirements

## Linux

* Install libx11-dev `sudo apt install -y libx11-dev`
* Install xvfb `sudo apt install -y xvfb`
* Initailize a frame buffer `Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 & export DISPLAY=:99.0` (You will need to do this everytime your reboot your server, I would add this to your .bashrc)

Add `export DISPLAY=:99.0` to your .bashrc (`nano ~/.bashrc`) file at the bottom

Add `@reboot Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1` to your crontab (`crontab -e`)
