Comment 32 for bug 1742602

Sorry about not finishing the bisection. I was dubious about the prospect of finding a nice clean patch to cherry pick in that drm-intel branch. But this is superseded now by the upgrade of linux-generic-hwe-16.04 to 4.15, which does not have the same issue.

I recommend closing this bug as fixed, and discussing the unrelated blank screen issues elsewhere. A blank screen is a failure mode, not a specific bug. Anyone seeing a blank screen in 4.14 or later is not experiencing the same issue. This was an i915 bug in the 4.13 kernel.
