Re: [Nouveau] [Bug 94990] Latest 4.6rc4 kernel, no booting on gtx970

[Efrem Mc]

In reference, I do use the nouveau driver on non-CUDA development systems.
I like how the development teams respond to bugs and fixes.  There are some
differences in the behavior of the kernels between 4.6.x and 4.7.x with the
video drivers.  I am not sure if is related to libdrm, mesa, of libGL
types.  I have a 960 GTX which is in the same product family as the 970
GTX.  Had problems with the 4.7.0 kernel and reverted back to the 4.6.5
kernel and working with some limitations.

I have to install the Nvidia driver on on development systems because I am
doing some programming with CUDA.  I use the CUDA Toolkit in C/C++.  I am
converting some of the software over to OpenACC.  OpenACC has it own
compilers but CUDA requires the non-free driver because the tools
communication to the driver with the APIs.

What version of the non-free Nvidia driver are you using? 370.23 or 367.35?

Hi QA:

 I had can to create the manual blacklist entry for nouveau.   I did this
because I wanted to use the non-free driver.  This is also required if you
want to use the Intel HD internal graphics card with a Nvidia chip set as a
secondary card.

The first edit will disable nouveau and verify by "lsmod | grep -i nouveau"



Manual edits required to get this working.

1. Created blacklist entry, /etc/modprobe.d/blacklist­nouveau.conf as shown
below

# cat /etc/modprobe.d/blacklist­nouveau.conf

blacklist nouveau

options nouveau modeset=0

2. kernel option used, nomodeset

Below (lines below) if you want to use the Nvidia non-free driver support:

3. Used Nvidia xconfig tool, nvidia­xconfig

4. Edit the file manually to see what drivers were being used , it should
state: Drivers “nvidia”

5. ** Special note, I have two separate video GPU cards and decided to use
individual heads, device1, device2


Now after booting, Nvidia drivers are working because the X server came up.
I noticed that

'num­lock' was off. Verification of X is as follows:

1. Verify what is in proc, lsmod, dmesg messages

# cat /proc/driver/nvidia/version

NVRM version: NVIDIA UNIX x86_64 Kernel Module 352.30 Tue Jul 21 18:53:45
PDT 2015

GCC version: gcc version 4.8.3 20140106 (OpenMandriva Association) (Linaro
GCC 4.8­2014.01)

This is the driver we wanted, 352.30, installed from 'mcc'; manual edits
required for the blacklist

file creation. The installation needs to create something. The Nvidia
installer does create a file for

you using their manual installation method by executing the driver
installation .run.

2. Verify X log in /var/log/Xorg.0.log.

3. Run Nvidia settings and Nvidia System Management Interface tool,
nvidia­settings, a X tool,

and nvidia­smi, System Management interface tool

Nvidia­smi, reports the driver version match such as in
proc/driver/nvidia/version and reports the

GPU(s). GPU­0, is the 960; GPU­1, is the 730 card. I want to run the 960 as
the primary (a

physical connection to a 24in monitor).

PS, I have used this in the past.  You can also try using "acpi_osi=Linux"
on the kernel command line.
This allows be to boot with the Nvidia card as a primary video source with
the Intel HD graphics card disabled in BIOS.

I have found that the BIOS is disabled and initfs still loads the i915
driver module

I had something similar with a VGA compatible controller: NVIDIA 
Corporation G84 [GeForce 8600 GT] (rev a1)


YaST2/mkinitrd.log:W: Possible missing firmware 
"nvidia/gm204/acr/bl.bin" for kernel module "nouveau.ko"

Same message for all .bin files on openSUSE Tumbleweed.

The files were all there under /lib/firmware/nvidia/gm204.
Forcing a reinstall of the kernel-firmware package solved it.

Sid.
