Sorry, I'm not familiar with English.

Adjustment of screen brightness might have failed .
Please try to press F7 key to increase screen brightness.
If F7 key does not work, I can not fix this issue .

大丈夫私は戻ってきたと私は何かを発見しました！だから私は、ラップトップに、テレビにVGAケーブルを差し込むか、それが動作します監視し、黒い画面に進みません。これは何かをすることを願っていますし、あなたはそれが可能な限りすぐに返事修正することができます。

I believe this would be failure of the kernel VGA driver(i915) . It's difficult for me to fix driver's failure .
In the next major version R52, kernel version up to 4.4 from 3.14 .
Please wait and try R52.

When will that be released

[crosbuilder]

See this url ("Estimated* Stable Dates")

https://www.chromium.org/developers/calendar

This is schedule of Chromium Browser, not Chromium OS.
Chromium OS release would be after about a week, then I'll start building. The build will take more than a week.

But, I can not promise that this problem will be fixed in R52.

okay

I tested R52 and kernel 4.4 , and found a degraded bug in the suspend function .
The failure does not occur in kernel 3.14 .
So, I decided to use kernel 3.14 in the next release.
Once the bug has been fixed , I'll use 4.4 .
There is no excuse, but please understand .
