title: MESA_GL_VERSION_OVERRIDE is not changing version string in Ubuntu 18.04 with nouveau
body: <p>I am trying to override the detected opengl implementation version (a fix for Dying Light on Steam). From my understanding of opengl, i should be able to set what version it is reported as via the MESA_GL_VERSION_OVERRIDE variable.</p>
  
  <pre><code>$ glxinfo | grep 'version string'
  OpenGL version string: 3.3 (Compatibility Profile) Mesa 19.0.8
  
  $ MESA_GL_VERSION_OVERRIDE=3.3 glxinfo | egrep 'OpenGL version string'
  OpenGL version string: 3.3 (Compatibility Profile) Mesa 19.0.8
  </code></pre>
  
  <p>How can I get gl to report as "3.3" and not the rest of it? I have tried exporting the variable too.</p>
  
  <p>Background: The Dying Light game checks for the version of gl, when I try run it, it crashes: </p>
  
  <pre><code>Detected OpenGL Version: 3.3 (Compatibility Profile) Mesa 19.0.8
  Required OpenGL version: 3.3
  Please update your display driver.
  </code></pre>
  
  <p>There's a few posts here and on the steam site that suggest using the variable, but the compat check still fails </p>
