title: Changing keyboard keys on new Ubuntu 18.04, xmodmap not working any more?
body: <p>I have upgraded my ubuntu to the latest 18.04 version and now my manual set shortcuts for some symbols on the keyboard are not working any more.</p>
  
  <p>Usually I was doing it by executing the following command:</p>
  
  <pre><code> xmodmap -e "keycode  15 = 6 ampersand 6 asciicircum bar fiveeighths"
  </code></pre>
  
  <p>But after the upgrade, this doesn't work any more. By pressing alt+key 6 I am not getting the "and" sign as I should. </p>
  
  <p>Is xmodmap not available any more? Is there some other solution?</p>
