I'm using Amazon Linux. I want to run a headless chromium browser to use on my node.js Selnium tests. So I fire up my Xvfb server like so ...
if ! pidof /usr/bin/Xvfb; then Xvfb :0 -screen 5 1024x768x8 & fi
However, when I try and take a screenshot after my tests have failed,
DISPLAY=:0 import -window root /tmp/screenshot.png
I get the error mentioned below...
+ DISPLAY=:0 + import -window root /tmp/screenshot.png import: unable to open X server `:0' @ error/import.c/ImportImageCommand/369.
How do I take a screenshot of Xvfb buffer?
