title: Upgrading GLX to version 1.3 on Ubuntu 18.04
body: <p>I have the following question: for the purpose of visualisation of some point clouds with GLFW library and Open3D, I would like to upgrade GLX to version 1.3 on Ubuntu 18.04. Having done some research on the Internet, I applied the most commonly advised solution:</p>
  <p><code>sudo add-apt-repository ppa:xorg-edgers/ppa</code></p>
  <p><code>sudo apt-get update</code></p>
  <p><code>sudo apt-get upgrade</code></p>
  <p>but to no avail - <code>glxinfo | grep version </code> still yields 1.2. Could it be driver-related? My graphics card is GeForce RTX 2070 and my driver is 460.32.03. I also seem to have the newest version of the Mesa library.
  I am running out of ideas and will greatly appreciate any help!</p>
