<pre>Hello,
I was redirected here from the archlinux IRC chat, hoping that this is the
correct place to file this bug.
I recently updated my archlinux kernel from 4.6 to 4.7 and my laptop screen is
fully dead now (backlight still on). I am using an intel cpu/gpu 4000 with the
builtin kernel drivers (no additional intel driver of arch).
This monitor is displayed in the xfce monitor config though. If i switch to
tty1 there is no output at all on the laptop. My 2 external displays work. If I
turn one off, this doesnt affect the laptop screen.
When booting I need to unlock my root partition (encrypted). This message is
actually displayed on the laptop screen at the initial step when systemd was
loaded. I am using EFI, but I can also boot MBR.
Switching back to 4.4 LTS kernel solves this problem.
My hardware is the following:
model name : Intel(R) Core(TM) i7-4702MQ CPU @ 2.20GHz
Its an Fujitsu Lifebook E744.
dmesg:
<a href="https://gist.github.com/NicoHood/3e515f96b522fc1ae0d6a781ce00ff58">https://gist.github.com/NicoHood/3e515f96b522fc1ae0d6a781ce00ff58</a>
Let me know of any additional information that I should provide.
I did not open a bug anywhere else yet, as people directed me here first. In
the meantime I will try the mainline kernel and report results back.</pre>
