hashcat beta and ubuntu 16.04 summary

[hashcrash]

This is my first post after reading a lot in this forum. I just finished setting up the hardware of first my rig, which I will document in a different post later. I quickly installed ubuntu 16.04 and got hashcat running for my GTX 980 and 1070.

By the way: I solved the "out of range" problem (HDMI related?) by "disabling" the cards first (my motherboard got switches for that), booting with the onboard GPU and installing the NVIDIA Driver.

But I get the same warning about the initial fan speed like in this post. I guess that it messed up something with one of commands that found in the forum trying to set up the nvidia or X11 settings. I'll start over with a fresh install in the next days.

I'd suggest to create a new bulletproof and tested HOW-TO like this one, but based on hashcat 3.0, ubuntu 16.04 LTS and nvidia drivers. I would test it with my GTX1070 and GTX980 and write the first version. The mentioned wiki article and atoms comments here are a nice baseline but I guess for newbies like me there are some things missing. We could add tuning tips for different nvidia cards which are flying around in the forum, but which aren't documented well (at least for hashcat 3.0).

Do I have to install a minimal X11-Environment (NVIDIA cards!)? You, atom, say no in the first post of this thread, but talk about the xorg.conf in the other one. I am mixing something up, huh? Furthermore nvidia-settings complains without X11.

Okay, lets start:

1. Install Ubuntu Server without anything except openssh.

2. Install some packages and disable multiarch (64-bit!): 

Code:

sudo apt install ocl-icd-libopencl1
sudo dpkg --remove-architecture i386
sudo apt update && sudo apt upgrade
sudo sync && sudo reboot

3. Add some repos and install the latest nvidia drivers (that means currently 367, correct?): 

Code:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install --no-install-recommends nvidia-367 nvidia-opencl-icd-367

Is this approach the same as the following? Which one is recommended?

Code:

wget http://de.download.nvidia.com/XFree86/Linux-x86_64/367.35/NVIDIA-Linux-x86_64-367.35.run
sudo ./Linux-x86_64/367.35/NVIDIA-Linux-x86_64-367.35.run

4. Install Intel-GPU-Stuff:

Code:

sudo apt install beignet-opencl-icd

5. Install Intel-CPU-Stuff (do I really need the full sdk or just the runtime?):

Code:

wget something
unzip someting
run something

6. X11 Stuff? I am referring to this post. What do I exactly have to set up?

7. Configure nvidia-settings and nvidia-xconfig.  Special things for the different gpu models (980 vs 1070)? Here i ran into errors.

8. Install hashcat...

9. benchmark...
....

I stopped here to see if I'll run into errors again. 

What do you think about the idea of a new HOWTO? And please answer my questions (bold).
