Public bug reported:
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.
