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:
qemu-img create -f qcow2 /var/lib/libvirt/images/nixos_disk1_100G.qcow2 100G
boot with nixos iso and create partitions:
parted /dev/vda -- mklabel gpt parted /dev/sda -- mkpart ESP fat32 1 1GB parted /dev/sda -- mkpart primary linux-swap 1GB 8GB parted /dev/sda -- 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, ... }:

}
configure static ip networking:

} ];

configure desktop gnome:

enable virtualization:
virtualisation.libvirtd.enable = true;
enable flatpak:
services.flatpak.enable = true;
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" ];
or nvidia gpu legacy drivers:
services.xserver.videoDrivers = [ "nvidiaLegacy390" ]; services.xserver.videoDrivers = [ "nvidiaLegacy340" ]; services.xserver.videoDrivers = [ "nvidiaLegacy304" ];
amd gpu drivers:
services.xserver.videoDrivers = [ "amdgpu-pro" ];
for laptop touchpads:
services.xserver.libinput.enable = true;
load kernel modules:
boot.kernelModules = [ "fuse" "kvm-intel" "coretemp" ];
load kernel modules on initrd:
boot.initrd.kernelModules = [ "cifs" ];
run the installer:
nixos-install
reboot the system:
reboot
