title: Ubuntu 18.04 update hibernate hangs
body: <p>After updating ubuntu 16.04 to 18.04 I can't get hibernate to work.</p>
  <p>I tried everything:</p>
  <blockquote>
  <p>sudo -s</p>
  <p>echo platform &gt; /sys/power/disk</p>
  <p>echo disk &gt; /sys/power/state</p>
  </blockquote>
  <p>and</p>
  <blockquote>
  <p>sudo -s</p>
  <p>echo shutdown &gt; /sys/power/disk</p>
  <p>echo disk &gt; /sys/power/state</p>
  </blockquote>
  <p>and</p>
  <blockquote>
  <p>sudo apt-get install uswsusp</p>
  <p>sudo s2disk</p>
  </blockquote>
  <p>and</p>
  <p>installed hibernate 2.0+15+g88d54a8-1.deb</p>
  <blockquote>
  <p>sudo hibernate</p>
  </blockquote>
  <p>In every case the computer hangs on a blank screen and never shuts down.
  On the other hand, suspend is working. But I need to save to disk so I can unplug the pc.</p>
  <p>does anyone have this problem and solved it?</p>
