  Ubuntu 17.04/17.10 Screen Tearing on Intel KabyLake Graphics Cards

Status in linux package in Ubuntu:

Bug description:
  Upon upgrading to 17.04 (also confirmed in 17.10), heavy, almost
  constant screen tearing presents itself immediately at the graphical
  or text splash page (i.e., before the operating system loads).  The
  tearing continues after reaching the lock screen and logging in.  The
  tearing is nearly constant, stopping only for certain actions like
  using the mouse or typing.

  The screen tearing can be "fixed" by issuing i915.enable_rc6=0 in the
  boot parameter.  However, this is a false fix as it turns off
  important power management functions and, as a consequence, the fan
  runs constantly and on high.
