Severity: normal
Classification: Unclassified
OS: Linux (All)

This is a reopen for #34554. If I'm wrong to report a new issue, please excuse
me.
On my Macbook Pro 6,2 (mid 2010) (coincidentally the same as in the above bug),
I was suddenly presented with an entirely black screen at a certain boot
(morning Dec 29th), and ever since. I did not make any system changes before
that cold boot. I do remember the system not shutting off properly the night
before.
Symptoms are the same (I have not tested other OSes):
Black internal screen (no backlight) all the way, even the grey EFI bootloader
screen is not there. PRAM reset works as normal (and should reset brightness so
that is not it). Looked at by Genius bar and they suspected a disconnected LVDS
cable, but that does not seem to be the problem.
External monitor works from the linux boot console kernel output on, but no
grey EFI bootloader screen. When external monitor is connected, the keyboard
lights up as well.
In the dmesg (with external monitor connected):

The line with "DDC responded, but no EDID for LVDS-1" repeats often.
Significant is that these long EDID reports only show up from the 29th onwards,
as well as on the last boot of the 28th (boot before the problematic boot).
That last boot shows:

As to the recommendation to try the latest updates, my mint system is up to
date (slight updated after problem occurred). Versions:
xorg 1:7.7+1ubuntu4
xserver-xorg-video-nouveau 1:1.0.7+git20130516.bf72ae1f-0ubuntu0sarvatt~raring
libgl1-mesa-dri 9.2.0~git20130627.15085b47-0ubuntu0sarvatt~raring
kernel 3.8.0-25-generic
As you can see, neither kernel nor nouveau are at the requested highest
versions, but these do not seem easily available for my distro. With some
pointers I can try them but am not sure what they would fix as corruption has
already occurred.
I will now proceed and try to repair.
