Question

I have Ubuntu 11.04 I am trying to install Xvfb and CutyCapt in order to take a snapshot of webpage I followed a instruction https://github.com/jaequery/cutycapt-installer-scri

Answer 1

Run xvfb-run -e /dev/stdout [mycommand] as @wumpus suggested.

I received the server lock message:

Fatal server error:
Could not create server lock file: /tmp/.X99-lock

xvfb-run: 

error: Xvfb failed to start

Using sudo resolved the issue for me:

sudo xvfb-run -e /dev/stdout [mycommand]
