I'm trying to run Firefox in Headless mode in a CentOS Linux release 7.0.1406 (Core)
I have already have firefox-45.3.0-1.el7.centos.x86_64 installed.
I have run the following commands for the configurations:
// install Xvfb package
yum install xorg-x11-server-Xvfb
// add screen resolution
Xvfb :99 -screen 0 1024x768x24 &
// add Display
export DISPLAY=:99
// run firefox
firefox
After running the firefox, have encountered this error: "Xlib: extension "RANDR" missing on display ":99"."
I have tried to add this extension using:
Xvfb :99 -screen 0 1024x768x24 +extension RANDR &
But stil, the same error persist when I attempt to run the firefox again.
How can I add RANDR in Xvfb when running in firefox?
Thanks for the response in advance.
