Hi,<br><br>I&#39;m trying to run the empty worlds on both Player Stage and Gazebo, but I get the same error on both occasions. <br><br>Xlib:  extension &quot;GLX&quot; missing on display &quot;:0.0&quot;.<br>Insufficient GL support<br>
<br clear="all">Has anyone encountered this and/or knows how to fix it? Thank you!<br><br>-- <br>Sebastian Castro<br>Mechanical &amp; Aerospace Engineering<br>Cornell University, Class of 2010<br>
