Unable to open X display when trying to run google-chrome on Centos (Rhel 7.5)

by

You can try with Xvfb. it does not require additional hardware.

Install Xvfb if you didn’t install it yet and do the following steps.

sudo apt-get install -y xvfb

Dependencies to make “headless” chrome/selenium work:

sudo apt-get -y install xorg xvfb gtk2-engines-pixbuf
sudo apt-get -y install dbus-x11 xfonts-base xfonts-100dpi xfonts-75dpi xfonts-cyrillic xfonts-scalable

Optional but nifty: For capturing screenshots of Xvfb display:

sudo apt-get -y install imagemagick x11-apps

Make sure that Xvfb starts every time the box/vm is booted:

Xvfb -ac :99 -screen 0 1280x1024x16 &
export DISPLAY=:99

Run Google Chrome

google-chrome
