body: <p>I installed Linux on an Intel Panel PC. Jockey cannot detect any drivers. I do not know how to install my graphics driver first so that I am be able to install touch screen.</p>
  
  <p>Here's some info from <code>dmesg</code>:</p>
  
  <p>dmesg | grep vga</p>

  <p>As I searched more, I think the graphics driver is installed by default, but I have no idea how I can check it availability in my system.
  sound driver is installed correctly.</p>
