    Description

      The documentation says:
      Xvfb screen changes the screen resolution and pixel depth, it needs to be in WxHxD format (i.e. 1600x1200x24). The default is 1024x768x24.

      I just installed the xvfb-plugin, and took all the defaults, leaving the "screen" value blank. When running my Jenkins job, the first time, in the log I could see:

      Xvfb starting$ Xvfb :1 -screen 0  -fbdir /var/lib/jenkins/xvfb-99-1021388786522495009.fbdir
      

      and at the end of the job:

      Xvfb stopping
      Finished: SUCCESS 
      

      Running the exact same job every subsequent time, the log say:

      Xvfb starting$ Xvfb :1 -screen 0  -fbdir /var/lib/jenkins/xvfb-100-2665068639033469958.fbdir
      
      ERROR: Xvfb failed to start, consult the lines above for errors
      

      Looking at running jobs (using `ps -ef | grep -i xvfb`), I got nothing.

      Trying this same command from the command line interface, I get:

      $ Xvfb :1 -screen 0  -fbdir /var/lib/jenkins/xvfb-106-4356636144193454909.fbdir
      
      Invalid screen configuration -fbdir for -screen 0
      

      Finally I decided to specify something for the "screen" parameter - I used the supposed default: "1024x768x24" - and everything worked fine.
