Try selecting CONFIG_DRM_KMS_HELPER and CONFIG_DRM_KMS_FB_HELPER. Also maybe CONFIG_DRM_FBDEV_EMULATION

For VGA arbiter, i lack the kernel support CONFIG_VGA_ARB but how is that going to do anything when there is only one GPU ?

Quote:
VGA Arbiter
===========

Graphic devices are accessed through ranges in I/O or memory space. While most
modern devices allow relocation of such ranges, some "Legacy" VGA devices
implemented on PCI will typically have the same "hard-decoded" addresses as
they did on ISA. For more details see "PCI Bus Binding to IEEE Std 1275-1994
Standard for Boot (Initialization Configuration) Firmware Revision 2.1"
Section 7, Legacy Devices.

The Resource Access Control (RAC) module inside the X server [0] existed for
the legacy VGA arbitration task (besides other bus management tasks) when more
than one legacy device co-exists on the same machine. But the problem happens
when these devices are trying to be accessed by different userspace clients
(e.g. two server in parallel). Their address assignments conflict. Moreover,
ideally, being a userspace application, it is not the role of the X server to
control bus resources. Therefore an arbitration scheme outside of the X server
is needed to control the sharing of these resources. This document introduces
the operation of the VGA arbiter implemented for the Linux kernel.

upgraded to nvidia-drivers 367.35-r1
https://devtalk.nvidia.com/default/topic/950630/unix-graphics-announcements-and-news/linux-solaris-and-freebsd-driver-367-35-long-lived-branch-release-/

Quote:
Release highlights since 367.27:
Fixed a regression that could cause console corruption when resuming from suspend.
Improved buffer write performance of the nvidia-drm DRM KMS driver by using write-combined DRM Dumb Buffers where available.
Fixed a bug that caused X to crash when applying changes to the RandR CscMatrix property while VT-switched away from X.
Fixed a bug that caused a crash when exiting nvidia-settings on displays with 8 or 15 bit color depths.
Added support for querying clock values on Pascal GPUs.
Removed the Base Mosaic configuration option from nvidia-settings on systems where the feature is not actually supported.
Fixed a bug that caused nvidia-smi to report an inaccurate version number.
Fixed a bug that prevented nvidia-bug-report.sh from finding relevant messages in kernel log files.
Added /var/log/dmesg to the list of paths which are searched by nvidia-bug-report.sh for kernel messages.


Stuck at the moment with the following while loading modset with drm:

modprobe -r nvidia_drm; modprobe nvidia_drm modeset=1

or:

4. add options nvidia_drm modeset=1 to /etc/modprobe.d/nvidia.conf

or adding nvidia_drm.modeset=1 to kernel boot parameters

Results in the following:

Code:
[ 3949.143149] [drm] [nvidia-drm] [GPU ID 0x00000100] Loading driver
[ 3949.143665] nvidia-modeset: Allocated GPU:0 (GPU-...................) @ PCI:0000:01:00.0
[ 3949.292382] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
[ 3949.292387] [drm] No driver support for vblank timestamp query.


When starting X:

Code:

[  4045.471] (II) modeset(G0): using drv /dev/dri/card0
[  4045.471] (EE) No devices detected.
[  4045.471] (EE) Fatal server error:
[  4045.471] (EE) no screens found(EE)
[  4045.471] (EE)


Problem seems to be [drm] No driver support for vblank timestamp query and the web does not help that much.
