To add extra detail, the above configuration results in xserver failing to start up. And goes into a loop, then the screen goes blank.
So I've not been able to successfully run the X GUI on the server either. But when I disabled the xserver, and just go straight to tty1, I only get nvidia-smi showing only 3 GPUs.
If I don't disable xserver and it's still breaks, I switch to tty2/tty3, and run nvidia-smi and only shows 3 GPUs.
I know you said this isn't an optimus solution, but in the prime render offload solution, Turing GPUs should be able to completely power down after some power management tweaks.
Otherwise, I don't know if I remember it correctly, but from what I can recall I think that to use the GPUs for compute only purposes, they still need to be in the Xorg configuration, but they have to be explicitly configured to not be used for the display.
Ran into this issue as well. Looks to be a permissions issue on my system.
@CMCDragonkai can you try sudo nvidia-smi
vs nvidia-smi
? On my system sudo
always reports the correct number of GPUs.
Probably related are udev failures:
Invalid value "/nix/store/wd1jazzawjk4w1d31ism7fm7vdg4ma9l-bash-4.4-p23/bin/bash -c 'mknod -m 666 /dev/nvidia-uvm c $(grep nvidia-uvm /proc/devices | cut -d \ -f 1) 0'" for RUN (char 102: invalid substitution type), ignoring, but please fix it.
That does looks like a rule that, if skipped, would result in this behaviour.
@coreyoconnor I can try that and report later. But I would like to know how to achieve what @eadwu mentions. How do I get the intel onboard VGA working while having the nvidia driver activated for only compute for the 4 GPUs? Consider that I'm not even able to get xserver properly started atm.
So this bug is actually 2 things:
Perhaps if 1. gets solved, then 2. gets solved too.
Note that I have of course used this kind of configuration for many other workstations that have GPUs as well and I've never had a problem in starting xserver until now.
For reference, this is what Ubuntu reports:
This is what NixOS shows:
Notice that even the performance setting is different. Also the power usage. NixOS is setting the GPUs on P0 setting and running the temperature higher.
If you're talking about prime render offload, it'll need patches to nixpkgs since it hasn't been merged to master yet. The core patch for the feature is contained in https://github.com/NixOS/nixpkgs/pull/66601. I don't know how much you'll actually be suspending or hibernating but if you ever want to do those you probably want https://github.com/NixOS/nixpkgs/pull/73530 as well. There's also https://github.com/NixOS/nixpkgs/pull/73167 for the latest release for NVIDIA. For the "experimental" PM for Turing GPUs, you probably want to look here [1].
Also just a warning but I have no clue how this works with multiple GPUs since NVIDIA users are pretty sparse as is here and most of us only have an iGPU and dGPU so yeah.
[1] https://download.nvidia.com/XFree86/Linux-x86_64/440.26/README/dynamicpowermanagement.html
So uh, while I was typing this I kinda came to the realization that I assumed that render offload would only have 1 dGPU from my setup and that isn't really required but due to it, it wouldn't really work with multiple GPUs as of yet.
@eadwu I don't know what you're talking about. This problem doesn't have anything to do with prime or optimus, and this system is not a laptop, its a big giant server that will not be hibernating ever.
@coreyoconnor I have tested with sudo nvidia-smi
, it ended up working.
So what happened is that nvidia-smi
first showed only 3/4.
Then I ran sudo nvidia-smi
, and I ended up with 4/4 GPUs.
Then subsequent runs of nvidia-smi
shows 4/4 GPUs without the need of sudo
.
That's really strange. So what's causing this problem? I should also mention that nvidia-smi
seems to lag a bit, and on NixOS it's all P0 states, whereas on Ubuntu I get P8 states.
I had to change back xserver.videoDrivers = [ "intel" "nvidia" ];
in order to even get the nvidia-smi
command.
Also the xserver
keeps failing, and I have took a video of the actual log taken from journalctl
of display-manager.service
. No matter what it keeps failing.
In the video, the error starts at:
(II) Module "ramdac" already built-in
(EE) No devices detected.
(EE)
Fatal server error:
(EE) no screens found(EE)
(EE)
Please consult the The X.Org Foundation support at http://wiki.x.org for help.
(EE) Pleas also check the log file at "/dev/null" for additional information
(EE)
(EE) Server terminated with error (1). Closing log file
Can't attach video, so here are screen shots of the relevant parts:
Also I found this issue with No monitor specified for screen "Screen-intel[0]"
and No monitor specified for screen "Screen-nvidia[0]"
, not sure if this is a problem as well, if that means we need to specify a default monitor for intel, and not for nvidia:
I had to change back xserver.videoDrivers = [ "intel" "nvidia" ]; in order to even get the nvidia-smi command.
Somewhat unrelated but I had to do something similar to get my nvidia card working on my laptop, I even updated the wiki page at https://nixos.wiki/wiki/Nvidia to reflect this.
I was getting the exact same error, i.e.
Fatal server error:
(EE) no screens found(EE)
(EE)
It seems like unless you have intel
nixos can't even detect any screens. Maybe we should make a bug report about this topic?
@mdedetrich That problem doesn't exist on my pure-nvidia systems, that is systems that don't have an intel onboard video card. In those systems, my monitors are connected directly to the NVIDIA cards.
But this problem is for a server that has intel onboard graphics with a VGA connector that I use to connect to the screen. While the 4 GPUs have nothing connected to them since they are only used for compute.
And in my situation even if I have intel
and nvidia
added as video drivers, my X server still doesn't start.
At the moment, there are 2 problems.
sudo nvidia-smi
@CMCDragonkai does this server have error messages like the following in the journal:

Some extra tests I've done on an "optimus laptop". Basically a laptop that has an integrated intel GPU and also an NVIDIA RTX 2070 GPU.
In the beginning the laptop has the same problem with xserver.videoDrivers = [ "nvidia" ];
. Basically X server doesn't start, and also nvidia-smi showed that the GPUs were at P0 state.
One thing that fixed this was xserver.videoDrivers = [ "intel" "nvidia" ];
. This solve the problem for the laptop. The X server started and the NVIDIA GPU is now at P8 state.
One thing that I'm confused about all of this. Is that I'm using Optimus at all. For example all of these options: https://nixos.org/nixos/options.html#optimus are irrelevant for the server. I'm not interested in shutting down the discrete GPUs when I'm not using them.
However for the laptop, I have not enabled any of these optimus settings either. But it appears that the laptop is capable of using intel for rendering and nvidia for compute in this case.
Am I right in guessing that enabling optimus would also potentially allow nvidia to render some windows (atm for the server/laptop, nvidia cannot be used to render, only compute). According to wikipedia:
Since driver version 435 the proprietary driver supports render offloading of a single window. It creates a virtual display where the dGPU renders to, which will be displayed in the window on the ma in screen for offloaded application.[10] As of October 2019 this requires usage of the xorg development branch, since needed modifications are not yet released.
Unfortunately for the server, having just xserver.videoDrivers = [ "intel" "nvidia" ];
is not sufficient to start the xserver.
This may be relevant: https://github.com/NixOS/nixpkgs/pull/66601 and will probably be the default method for any optimus laptops in the future.
@coreyoconnor Yes I do see it. Here is the output of journalctl -u systemd-udevd

Another way to solve this is to run this at bootup:
sudo nvidia-persistenced --persistence-mode
Seems like NixOS requires a persistenced service.
Solved with
systemd.services."nvidia-persistenced" = {
description = "NVIDIA Persistence Daemon";
wantedBy = [ "multi-user.target" ];
serviceConfig = {
Type = "forking";
Restart = "always";
PIDFile = "/var/run/nvidia-persistenced/nvidia-persistenced.pid";
ExecStart = "${pkgs.linuxPackages.nvidia_x11.persistenced}/bin/nvidia-persistenced --verbose";
ExecStopPost = "${pkgs.coreutils}/bin/rm -rf /var/run/nvidia-persistenced";
};
};
I just removed xserver since that was to test it. But since I don't have physical monitors and no other way to debug this it doesn't matter anymore. The nvidia-persistenced solves the original problem.
@CMCDragonkai Is this something that should be there by default? In which case it might make sense to make this an offical nixos option so its easier to solve for other people (and we should hence make an issue for it).
Yea it could be an option. It just means the GPUs are always on even in a headless system. Seems like what you'd want and we end up having 4/4 GPUs. I don't have time to create an option for it.
Okay I will file an issue for it then so that at least we have a reference for it.
On a server which I have 4x RTX2070 GPUs and Intel Onboard Graphics, when installing the 19.09 NixOS, and running nvidia-smi, I only see 3 out of 4 GPUs. It's always the first GPU that is missing.
When I switch to Ubuntu 18.04 (running Linux 5.0), and run nvidia-smi, I see 4 GPUs
Both systems are using the 435.21 drivers on RTX2070 GPUs.
On IRC, somebody else mentioned this problem and confirmed that they fixed it somehow, but it didn't quite work for me.
On the server, I need to use
intel
driver, because the display is driven by the VGA not the GPUs which use the onboard graphics.The GPUs are only meant for compute. And this is not an optimus situation.
This is my configuration (for the netboot system), I'm building on nixpkgs hash: f6dac8083874408fe287525007d3da9decd9bf44
