Hi! I tried nixos in a virtualbox machine, installed and it works.
Now i launched it from usb, everything is ok. Installed with plasma desktop, rebooted and now the desktop doesn’t start, i only see the shell.
I have a santech c88 with nvidia 3060 .
Thanks
Did you configure a desktop? Any errors in journalctl --boot -e? I think the last 20 people with iGPU+Nvidia with similar issues just had to configure this: Nvidia - NixOS Wiki
Edit: I can’t read
Hi! Thanks for your response. I checked the journalctl and there were several errors from nouveau drivers.
I I followed the guide, I no longer see nouveau’s errors but it still doesn’t start.

There is a Fatal error at line 824 but i don’t understand why
Hrm, just to double check, these are actually the ones from your device, right? They just happen to be the same as the ones in the wiki entry?
If so, perhaps remove the offload settings for now, and try setting these options: common/gpu/nvidia*: Migrate to common/gpu/nvidia/* and add non-prime by TLATER · Pull Request #502 · NixOS/nixos-hardware · GitHub
Just to confirm your system can actually boot.
The error says that xserver couldn’t find the bus ids for the GPUs.
You can try the lspci command to get the bus id(s). If you don’t have the lspci command, you can add pciutils to environment.systemPackages in your configuration.nix or use nix-shell to use it temporarily.
The command below will filter out PCI devices to ones with VGA or 3D or NVIDIA in their name and should show both an Intel integrated GPU and your NVIDIA RTX 3060 dedicated GPU:
lspci | grep -E "VGA|3D|NVIDIA"
The first block of text in each returned line will be the PCI bus id. You’ll need to make sure that these match your actual hardware in your configuration.nix by prepending “PCI:”, replacing any “.” characters with “:”, and removing leading zeroes (so “00:02.0” is listed in configuration.nix as “PCI:0:2:0”).
$ lspci | grep -i -E "VGA|3D|NVIDIA"
00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P Integrated Graphics Controller (rev 0c)
01:00.0 3D controller: NVIDIA Corporation TU117GLM [T600 Laptop GPU] (rev a1)
If that doesn’t fix your issue, then I’d recommend trying to get it to just boot to a desktop environment first, and then worry about Prime offloading or whatever after. Once of the nice things about Nix is the ability to experiment and then roll back if needed.
Below are some things you could try in configuration.nix. I’d try one change at a time, do nixos-rebuild boot or nixos-rebuild switch, and then reboot, painful as that may be. Maybe revert to a “default” config and then try the items below starting from there.
Comment out the line: services.xserver.displayManager.sddm.enable = true;. If I recall I had issues with sddm with nvidia, but the default lightdm worked fine.
Change the xserver driver from “nvidia” to “modesetting” services.xserver.videoDrivers = [ "modesetting" ];. This will use the nouveau driver instead of the proprietary nvidia driver. It should work fine, at least just to get the system to boot to a desktop environment.
This doesn’t work when two GPUs are fighting, which is where the thread started. You’ll want to disable the nvidia gpu entirely as here if you want to test if anything works.
Normally the nvidia GPU isn’t connected to the output directly, but the iGPU (in this case an intel one) is, which is why you need offloading.
Thank you both. I had to install another distro because I started work yesterday. I will try to install nixos side by side over the weekend and follow your advice.
Thanks again
