  Kubuntu Freezes / Crashes on Suspend to RAM

Status in xorg package in Ubuntu:

Bug description:
  Hardware is Lenovo Yoga 2 13.3 convertible. Unfortunately, I have two
  problems with suspend-to-RAM on Kubuntu 15.10.

  * Problem one is already reported in bug report 1418295: Sometimes,
  the screen freezes on resume. This seems to happen more often, when I
  happen to touch the touchscreen in the seconds of resume. As this is
  already a confirmed bug, no more info to it here.

  * Problem two - and the more serious problem - is, that the whole
  system freezes at the time of suspend-to-RAM, when it has been running
  for more than two hours since boot or last resume. So, if I remember
  to interrupt my work at least every two hours, press the power button
  (which I have set to perform suspend-to-RAM), and then immediately
  wake up the system again, I am fine. But if the system has run for
  more than two hours, and I then do the suspend-to-RAM, it freezes
  before the suspend: The screen turns black as it ought to in suspend-
  to-RAM, but the power does not go off and the CPU fan keeps running.
  Input is no longer possible. In this state, the only thing, that I can
  do, is a hard power-off: Press the power-button for over 5 seconds.

  This problem is very annoying.

  I've had this problem since original install with Kubuntu 15.04. An
  install to Kubuntu 15.10 in the last weeks didn't solve it.

  I tried to report this bug also with ubuntu-bug, but it ended with a
  segfault, after it displayed the aggregated data.
