title: What's the difference between xorg.conf, xset and xinput set?
body: <p>I don't understand why with xset and xorg.conf there are two things with exactly the same purpose but totally different options? Why are there two and not one? Why can't their parameters have the same names? And even in xorg.conf itself there are multiple options with different names and the same effect. Why is that so chaotic?</p>
  
  <p>For example I can deactivate my mouse acceleration in xorg.conf with</p>
  
  <pre><code>Option "AccelerationProfile" "-1"
  </code></pre>
  
  <p>or with</p>
  
  <pre><code>xset m 0 0
  </code></pre>
  
  <p>I use Arch Linux with Gnome 3 and Linux Kernel 3.0.26-1-lts.</p>
