BTW, I might note that vesa is being loaded... perhaps that's upsetting things,
although I'm not sure if that would do it.

There isn't a single mention of nouveau. I don't know why nouveau's not being
loaded, but there's not even an attempt of it. Please file a bug with your
distro.

To be clear, what I'm looking for is the output of dmesg. Not the output of
"dmesg | grep something".

This is true, I don't see from lsmod command,
video have 0 , in intel was driver i915.

In next day I will try save lsmod output, 
from dmesg I have only ACPI errors, nothing more from :
 dmesg |  grep -i 'error\|warning\|fail|\segfault'

Perhaps if you provide a dmesg, it will become apparent why nouveau didn't
load. Can't really tell that from the xorg log... it's just obvious that
nouveau isn't loaded.

It should be "it, as pointed out by Lukas Wunner", sorry for the mistake… :-/

[Nouveau] [PATCH v2 2/2] nouveau/bl: Do not register interface if Apple GMUX detected

2016-05-01 Thread Pierre Moreau 
The Apple GMUX is the one managing the backlight, so there is no need for
Nouveau to register its own backlight interface.

v2: Do not split information message on two lines as it prevents from grepping
it, as pointed out by Hans de Goede
