title: setGraphicsEventEnv() not supported under Linux?
body: <p>I'd like to run a script containing an interactive part on a Ubuntu 64 bit machine. Unfortunately it fails throwing the following error:</p>
  
  <pre><code>Error in setGraphicsEventEnv(which, as.environment(list(...))) : 
    this graphics device does not support event handling
  </code></pre>
  
  <p>Any hints how I can setup R such that it supports event handling? X11 should be supported according to the documentation.</p>
  
  <p>This examples fails on my machine with the error above:

  <p>Thanks!
