Please consult https://sources.debian.net/src/wkhtmltopdf/0.12.3.2-3/debian/README.Debian/ <https://sources.debian.net/src/wkhtmltopdf/0.12.3.2-3/debian/README.Debian/> which I’m quoting below: Due to its dependency on Qt-WebKit, wkhtmltopdf requires an X11 server to run. If you want to provide an automated service or use wkhtmltopdf from a webserver, it could be convenient to use a virtual X11 server (like Xvfb). The xvfb Debian package contains a wrapper which makes it trivial: xvfb-run -- wkhtmltopdf [options] -- Cyril Brulebois <k...@debian.org <mailto:k...@debian.org>>, Mon, 7 Feb 2011 01:11:31 +0100 Another way I found to overcome the display connection error and make it work without an X server is: QT_QPA_FONTDIR=/usr/share/fonts/truetype/dejavu/ QT_QPA_PLATFORM=offscreen wkhtmltopdf page.html index.pdf Unfortunately I could not find much documentation about the offscreen platform of Qt.
