NVIDIA Drivers - msf004 - 08-16-2016

Summary:
When I run any nvidia-settings command (such as nvidia-settings -a GPUPowerMizerMode=1 -a GPUFanControlState=1 -a GPUCurrentFanSpeed=90 -a GPUGraphicsClockOffset[3]=100) I get errors:

Code:
# sudo nvidia-settings -q GPUCurrentClockFreqs

** (nvidia-settings:18807): WARNING **: Could not open X display

Full Details:
Per other postings, I performed an "OpenSSH Server" install of Ubuntu 14.04.1.

I then d/l'ed the latest NVIDIA Drivers straight from the NVIDIA site: NVIDIA-Linux-x86_64-367.35.run

I Ran:

Code:
apt-get install -y build-essential p7zip unrar unzip

bash NVIDIA-Linux-x86_64-367.35.run 

apt-get install linux-headers-4.4.0-31-generic build-essential libx11* libxnvctrl-dev

dpkg --remove-architecture i386

aptitude update && aptitude full-upgrade

sync && reboot

Then, I found a few posts about some nvidia-settings commands for headless systems:

Code:
nvidia-xconfig -s -a --force-generate --allow-empty-initial-configuration \

    --cool-bits=12 --registry-dwords="PerfLevelSrc=0x2222" \

    --no-sli --connected-monitor="DFP-0"

sed -i '/BusID.*/a \ \ \ \ Option         "Interactive" "False"' /etc/X11/xorg.conf

...and lastly...

Code:
nvidia-settings -a GPUPowerMizerMode=1 \

                -a GPUFanControlState=1 \

                -a GPUCurrentFanSpeed=90 \

                -a GPUGraphicsClockOffset[3]=100

However, anything I do with the nvidia-settings command results in errors:

Code:
# sudo nvidia-settings -q GPUCurrentClockFreqs

** (nvidia-settings:18807): WARNING **: Could not open X display

ERROR: The control display is undefined; please run `nvidia-settings --help` for usage information.

...or...

Code:
$ sudo nvidia-settings -a GPUPowerMizerMode=1 -a GPUFanControlState=1 -a GPUCurrentFanSpeed=90 -a GPUGraphicsClockOffset[3]=100

error: XDG_RUNTIME_DIR not set in the environment.

ERROR: The control display is undefined; please run `nvidia-settings --help` for usage information.

Any suggestions what I could have done wrong or what I could do to correct this?

Thank you for any feedback, your assistance is appreciated.

What about /etc/X11/xdm/Xsetup? Does it contain this:

Code:
export PATH=/bin:/usr/bin:/sbin

export HOME=/root

export DISPLAY=:0

xset -dpms

xset s off

xhost +

And: ~/.bashrc and /etc/skel/.bashrc?

Code:
export DISPLAY=:0

Then run:

Code:
update-rc.d xdm defaults

sync && reboot

To be found here.

By the way: I finally installed to 14.04, because I did't get it running properly on ubuntu 16.04.

RE: NVIDIA Drivers - msf004 - 08-16-2016

So, I do not even have a /etc/X11/xdm directory. I have a /etc/X11 directory that contains:

-rw-r--r-- 1 root root 17394 Dec 3 2009 rgb.txt
-rw-r--r-- 1 root root 1494 Aug 14 12:46 XF86Config

-rw-r--r-- 1 root root 601 Aug 14 12:18 Xwrapper.config

It would appear maybe I overlooked or missing installing something? But the /etc/X11 dir is there, just not the Xsetup you mentioned.

Obviously, I could create that directory, but I am curious if I missed installing a package. Any thoughts?

RE: NVIDIA Drivers - msf004 - 08-16-2016

I know I did not perform this step from the link you provided: https://hashcat.net/wiki/doku.php?id=linux_server_howto

Code:
aptitude install build-essential dkms xserver-xorg xserver-xorg-core \

xserver-xorg-input-evdev xserver-xorg-video-dummy x11-xserver-utils fglrx xdm

However, from reading I was under the impression that step was only for AMD cards. Maybe I'll try that step on my rig and see if that helps.

RE: NVIDIA Drivers - hashcrash - 08-16-2016

I ran into the same mistake, but nvidia-settings seem to need that.

EDIT: Maybe we don't need fglrx for nvidia cards, right?

RE: NVIDIA Drivers - epixoip - 08-16-2016

You should not install fgrlx for nvidia cards, but the rest is all the same for both amd and nvidia.

RE: NVIDIA Drivers - msf004 - 08-16-2016

Thank you! Installing those packages corrected my issues.
