issue reproduce on 8696.0.0/54.0.2824.0 with speedy

just close/open the lid and can see issue

I don't see this on my minnie, and I don't have a speedy here.

dbehr, can you try this patch and see if it helps:

Any updates? Has the patch from #9 been tested?

I see a white flash when I open the lid on a veyron_speedy device to resume it. It repros every time.

katierh, can you help find someone to try this patch and see if it helps:
https://chromium-review.googlesource.com/368561

I see this all the time on my jerry device on beta channel and it's ugly.  I've been down in the lab and not up at my desk for about a month now so I haven't been able to test the patch myself.  Hopefully someone on this thread can.

sontis - can someone on your team help test? please ping on chat if you're missing devices

Can you point sontis@ to a image location with patched build to download and image speedy device?

Kicked off a magic build bot with the command:

$ cbuildbot --remote -g 368561 veyron_speedy-release

Eventually <https://uberchromegw.corp.google.com/i/chromiumos.tryserver/builders/release/builds/6022> will finish and then you can find an image in the Artifacts.

FYI that the build is done.  Test away.

 Issue 670010  has been merged into this issue.

commit 73099f19838bcad9f4ee4f882e97473ceee7e0b0
Author: Thierry Reding <treding@nvidia.com>
Date: Fri Mar 17 01:06:55 2017

UPSTREAM: drm/panel: simple: Update backlight state property

Some backlight drivers ignore the power property and instead only use
the state property. Fixup the panel driver to set the state property in
addition to the power property.
