g3 instances

[PolarNick239]

Thank you a lot for your scripts! :)

I was able to run OpenGL app on g2, and tried to do so on new g3 instances, but failed. Have you tried them? May be you will have some time to take a look?

My attempt on g3 differs from g2 in driver installation:

sudo apt update
sudo apt install -y awscli
# Configure awscli like described here - http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html#cli-quick-configuration
#  - Note that correct region names you can get here - http://docs.aws.amazon.com/general/latest/gr/rande.html#apigateway_region
#  - Default output format [None]: json
aws configure
aws s3 cp --recursive s3://ec2-linux-nvidia-drivers/ .
lspci | grep VGA
# Ensure that above command output contains this line:
# 00:1e.0 VGA compatible controller: NVIDIA Corporation GM204GL [Tesla M60] (rev a1) 
#
# Then change install-nvidia-drivers-g2.sh:
# 1) Remove driver download
# 2) Change BusID from 0:3:0 to 0:1e:0
./install-nvidia-drivers-g2_changed.sh

And then on starting X I encounter (/var/log/Xorg.0.log):

P.S. Also I tried suggestion from this topic:

After a bunch of testing, the solution is to not use nvidia-xonfig to generate xorg.conf. X.org won't start with the generated ServerLayout, Monitor and Screen sections (even with UseDisplayDevice "None"). The device section also needs an explicit BusID device added. 

A minimal working config is, e.g.:

Section "DRI"
	Mode 0666
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GRID M60-4Q"
    BusID          "PCI:2:0:0"
EndSection

P.P.S. Installation of sudo apt install xserver-xorg-video-cirrus seems don't help. But I will try again clean install after some time.

[PolarNick239]

I find that xorg.conf expects BusID in decimal, so 0:1e:0 -> 0:30:0, but now I stuck with this:

[   233.597] (EE) NVIDIA(GPU-0): UseDisplayDevice "None" is not supported with GRID
[   233.597] (EE) NVIDIA(GPU-0):     displayless
[   233.597] (EE) NVIDIA(GPU-0): Failed to select a display subsystem.

P.S. I will try to adopt those scripts.

Thanks a lot for your scripts! Seems to finally work! :)

It seems that I just needed to delete section ServerLayout and Screen in xorg.conf.
Also I am installing driver and configuring xorg.conf before VirtualGL configuration.

The final instructions that worked for me on g2 and g3 + Ubuntu 16.04:

• configuration (with manual part of editing xorg.conf!)
• start X and VNC servers

P.S. super final instruction for g2, g3, p2 and p3 - https://github.com/agisoft-llc/cloud-scripts

Thanks @PolarNick239 for your investigation :-) I'll take a look once I'd be about to run on g3. Up till now g2 have been enough for my needs, but that could change soon!
Cheers.

@PolarNick239 you are an absolute beast. Thanks, this just got paraview working for me on a g3 instance! 😄
