<pre>Hi we bought a batch of laptops NP900X5N with i7-7500 (Kaby) 16MB ram. When I
run Linux from a stick (live usb and/or installed as on a ssd), I see the exact
same behavior as described by Phil. The screen goes black after a random while,
and stays black.
We need to resolve the issue to deploy Linux on the machines.
First analysis:
Various Linux distributions until the latest 4.18 kernel and disabling TMP
makes no diff. The dmesg gave a number of errors that was resolved with
i915.modeset=0 nouveau.modeset=0 and TMP off. I played around with some modeset
settings and that resulted ONCE in disabling the brightness adjustments and no
black screens anymore. I'm now trying to reproduce that.
If needed I can provide logs for you guys.
Hope I can be of help (merely testing and providing info) to resolve the issue
and enable Linux on the machines.</pre>
