Hi Ben, David and Daniel ,
First of all happy new year. Based on advice of Greg K-H herewith a mail
about a number of Nouveau issues with my laptop.
I installed various Kali linux versions up to Linux 4.20.0-rc7
(downloaded, compiled and installed) on a Samsung NP900X5N laptop and
have an issue with the driver after loading.
My configuration:
- i7 7500
- 16 gb / 256 gb ssd
- nvidia 940MX (for 3D graphics)
When I enable loading of the nouveau module for my Nvidia 3D card I get
three MMIO faults:
[ 35.984104] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 6013d4 [ IBUS ]
[ 35.997510] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 10ac08 [ IBUS ]
[ 37.551790] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 619444 [ IBUS ]
I see currenty varous discussions on bugzilla: (as summarized by Bruno
Pagani) https://bugs.freedesktop.org/show_bug.cgi?id=100423.
But I do not see any confirmed solutions on the MMIO faults.
The module is loaded but X server cannot run in framebuffer mode. I
assume that the module does not provide any video memory to X to run in
graphics mode.
First of all I would like to understand what the faults impose.
And I also would like to help you providing testing to fix the errors.
Many thanks for your kind support.

The faults are, generally, nothing to worry about, esp if they occur
infrequently. It's one bit or another of code that's poking at a part
of the GPU it shouldn't be touching.
To the best of my knowledge, 940MX (GM108) should work reasonably
well. Perhaps it would make most sense if you posted about some of
your other issues (usually GM108's are have no outputs, so only usable
as offload devices). Feel free to join #nouveau on irc.freenode.net to
get more info as well.

Unless you're an advanced user, you'll get the best results by not
supplying a manual xorg.conf. Generically, this indicates that you
messed something up. Without knowing precisely what the contents of
that file are, it would be difficult to say what exactly went wrong.
However I wouldn't advise this path without a good reason.

It's an IRC network like any other. More info about the network
available at https://freenode.net/
It's open to anyone... #nouveau for nouveau, #intel-gfx for intel.

I don't know the specifics of your laptop, but on many other GM108M
laptops, the displays are only attached to the Intel GPU. So running
without i915 is just not an option, if you want anything displayed.
You would be able to use the GM108M chip for 3D acceleration if you
chose, but nothing to do with actual display.
If your screen goes black with i915 loaded, I suspect that you'd be
better served reporting this issue to Intel.
From your logs, you also appear to have a variety of combinations of
nomodeset/<driver>.modeset=0 combinations -- these will just impede
the proper mode of operation. The i915 and nouveau drivers effectively
do nothing under those conditions.
