wkhtmltopdf 12.4 - QXcbConnection Could not connect to display

I'm getting an error (see below) and have looked through the many answers here but still have no idea how to get this to work:

ERROR "The exit status code '134' says something went wrong: stderr: "QXcbConnection: Could not connect to display Aborted (core dumped) " stdout: "" command: /usr/bin/wkhtmltopdf --lowquality '/tmp/knp_snappy595ac8ce820719.82188465.html' 'TEST_874041855595ac8ce809a93.09267749.pdf'"

SERVER I'm using a DigitalOcean Ubuntu 16.04 droplet with PHP 7.1 and Laravel 5.4 with Snappy and wkhtmltopdf version 12.4 64bit (everything works fine on my local Windows machine BTW), but I get the above error on the server. Here's my code:

CODE $rendered_output = new Pdf('/usr/bin/wkhtmltopdf'); $rendered_output->generateFromHtml(view('pdf')),'file.pdf');

INSTALLATION I installed wkhtmltopdf and updated the server using these commands: sudo apt-get update sudo apt-get install wkhtmltopdf

HELP Has anyone got any ideas how I can fix this please (even if it means using a different DO server and some other distro)? Thank you in advance.

I fixed this by doing two things:

  1. I installed xvfb on the server: sudo apt-get install xvfb

  2. I called xvfb: $snappy = new Pdf('/usr/bin/xvfb-run /usr/bin/wkhtmltopdf');
