Howto nixos
configure enviroment
download nixos installation iso:
https://channels.nixos.org/nixos-23.05/latest-nixos-minimal-x86_64-linux.iso
create usb to install on physical desktop:
yay -S ventoy-bin
or install nixos on virtual machine:
mkdir /var/lib/libvirt/images/nixos -p qemu-img create -f qcow2 /var/lib/libvirt/images/nixos/nixos_disk1_100G.qcow2 100G
boot with nixos iso and login as root:
sudo su -
configure static ip network:
ip addr add 192.168.75.44/24 dev enp1s0 ip route add default via 192.168.75.1 rm -rf /etc/resolv.conf echo "nameserver 4.2.2.1" > /etc/resolv.conf echo "nameserver 4.2.2.2" >> /etc/resolv.conf
configure wireless network:
systemctl start wpa_supplicant
run wpa_cli:
wpa_cli
configure your access point:
add_network set_network 0 ssid "mywifiname" set_network 0 psk "mypassword" set_network 0 key_mgmt WPA-PSK enable_network 0
leave wpa_cli:
quit
set password to root user:
passwd root
from another machine enter via ssh to nixos installation:
ssh root@192.168.75.44
create partitions:
parted /dev/vda -- mklabel gpt parted /dev/vda -- mkpart ESP fat32 1 1GB parted /dev/vda -- set 1 esp on parted /dev/vda -- mkpart primary linux-swap 1GB 8GB parted /dev/vda -- mkpart primary ext4 8GB 100%
format partitions:
mkfs.fat -F 32 -n boot /dev/vda1 mkswap -L swap /dev/vda2 mkfs.ext4 -L nixos /dev/vda3
installing os
mount root partition on /mnt:
mount /dev/vda3 /mnt
make boot directory and mount boot partition:
mkdir /mnt/boot mount /dev/vda1 /mnt/boot
mount swap partition:
swapon /dev/vda2
generate nixos configuration file:
nixos-generate-config --root /mnt
edit configuration file /mnt/etc/nixos/configuration.nix:
{ config, pkgs, ... }:

networking.defaultGateway = "192.168.75.1";
networking.nameservers = ["4.2.2.1" "4.2.2.2"];
configure wireless network:
networking.wireless.enable = true;
on terminal execute the following command:
wpa_passphrase mywifiname mypassword
add the following configuration to your configuration.nix:
networking.wireless = {
enable = true;
userControlled.enable = true;
networks = {

allow nonfree apps:
nixpkgs.config.allowUnfree = true;
configure desktop gnome:

enable bluetooth:
hardware.bluetooth.enable = true;
enable podman containers:
virtualisation = {

oci-containers.backend = "podman";
};
then when system boot configure flatpak repo:
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
system packages:
environment.systemPackages = with pkgs; [ wget vim nano zsh file lsof virt-manager ];
intel drivers:
services.xserver.videoDrivers = [ "modesetting" ];
if you experience screen tearing no matter what, this configuration was reported to resolve the issue:
services.xserver.videoDrivers = [ "intel" ]; services.xserver.deviceSection = '' Option "DRI" "2" Option "TearFree" "true" '';
nvidia gpu drivers:
services.xserver.videoDrivers = [ "nvidia" ]; boot.blacklistedKernelModules = [ "nouveau" ];
or nvidia gpu legacy drivers:
services.xserver.videoDrivers = [ "nvidiaLegacy390" ]; services.xserver.videoDrivers = [ "nvidiaLegacy340" ]; services.xserver.videoDrivers = [ "nvidiaLegacy304" ];
amd gpu drivers:
services.xserver.videoDrivers = [ "amdgpu" ];
for laptop touchpads:

load kernel modules:
boot.kernelModules = [ "fuse" "kvm-intel" "coretemp" ];
load kernel modules on initrd:

firewall is enabled by default, you can open specific tcp ports:
networking.firewall.allowedTCPPorts = [ 22 ];
run the installer:
nixos-install
reboot the system:
reboot
os configuration
add unstable channel:
nix-channel --add https://nixos.org/channels/nixos-unstable nixos-unstable nix-channel --update
run command without installing the package in your current session:
nix-shell -p git
verify current os configuration:
nix-shell -p nix-info --run "nix-info -m"
list current os generations:
nix-env --list-generations
command output:

custom pkgs
clone git repo:
git clone https://github.com/NixOS/nixpkgs.git /usr/local/nixpkgs
edit /etc/nixos/configuration.nix to import custom module:
{
imports =
[ # Include the results of the hardware scan.

(import "/usr/local/nixpkgs/nixos/modules/services/admin/nomachine.nix")
];
disable module on repo:

edit /etc/nixos/configuration.nix to import custom package:
nixpkgs.config = {
allowUnfree = true;
packageOverrides = pkgs:
{
nomachine = pkgs.callPackage (import "/usr/local/nixpkgs/pkgs/tools/admin/nomachine/default.nix") {};
};
};
services.nxserver.enable = true;

home-manager
install home-manager:
sudo nix-channel --add https://github.com/nix-community/home-manager/archive/release-23.05.tar.gz home-manager

add the following line:
home-manager.users.linux = { pkgs, ... }: {
home.packages = [ pkgs.home-manager ];
home.stateVersion = "23.05";
programs.bash.enable = true;
};
apply this configuration with rebuild:
sudo nixos-rebuild switch
create initial configuration:
home-manager init
edit ~/.config/home-manager/home.nix:
