I actually get some traces. There appears to be 2 different traces
that repeat whenever the screen goes through that turn off-turn on
cycle (but at first, only the first trace is shown).

I believe the screen turns itself off at the time this message is printed:
"Aug 26 07:25:04 nc052 kernel: [drm:i915_runtime_suspend] Suspending device"

First trace:
