Install Kernel from one of the following locations:

Christopher,
Yes I have read that section but it is not useful as selecting between bad/good
is already the required workflow. The issue is that the documentation refers to
using the packaging scripts in the debian/ subdir, which is not present and/or
usable in the intermediate bisecting steps.
I have tested 4.0.0-13 which does not seem to exhibit the flickering
present from 4.0.0-9 to 4.0.0-12. It does however now present tearing
artifacts when switching focus between windows, see
