Hi Ilia, many thanks for answering my mail. Tonight I tried to see what happens if I generate a xorg.conf file and place it in /etc/X11/xorg.conf, as described here: https://askubuntu.com/questions/4662/where-is-the-x-org-config-file-how-do-i-configure-x-there When I do that X starts without the framebuffer error. X starts with a backtrace list in the shell and then stops with the error: 'Segmentation fault at address 0x0. Fatal sever error etc etc etc. Hope this helps!In fact the above is part of a much bigger issue I have with the machine. When I enable the i915 module (Kaby lake native video) my screen goed black after a while. The machine is totally stuck in that state. Even ssh connection is not possible. It shows no errors in the (saved) logs after restarting the machine.
So I disabled the i915 module and try to get the nvidia card running. Without any luck.
Thank you for inviting me for irc.freenode.net. What it the procss to get access?
I have included the full dmesg in zip format.For me it is a showstopper using the machine with Linux. I really do not understand that I am the only person on this planet that cannot run Linux on a plain vanilla Kaby lake machine.

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.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. Cheers, -ilia
