Dear Maintainer,

When testing the linux-image-3.14-rc7-amd64 package from experimental, I
discovered an issue with the handling of the internal laptop display.

The system boots but shortly after the kernel has loaded, the internal laptop
display goes blank. If an external display is connected, the system displays
boot messages on the external display instead of the internal display. If xorg
is started, only the external displplay is usable -- the internal display
remains black. Closing the laptop lid and opening it reactivates the internal
display.

I was able to find an upstream bug [1] which may be relevant.

I do not experience this issue with the 3.13 kernel.

Thanks for letting us know.

One of the nice things about standards is that there are so many of them.
