# NixOS Installation Guide for ThinkPad P14s Gen 2
|
||||
|
||||
This guide will walk you through installing NixOS on your Lenovo ThinkPad P14s Gen 2 with Intel i7 and NVIDIA T500 GPU.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- USB drive (4GB or larger)
|
||||
- NixOS ISO image
|
||||
- Ethernet cable or WiFi credentials
|
||||
- This configuration repository
|
||||
|
||||
## Step 1: Prepare Installation Media
|
||||
|
||||
1. Download the latest NixOS ISO (GNOME or Plasma edition recommended for GUI installer):
|
||||
```bash
|
||||
# Download from https://nixos.org/download.html
|
||||
# Choose the 64-bit Intel/AMD ISO
|
||||
```
|
||||
|
||||
2. Write the ISO to USB drive:
|
||||
```bash
|
||||
# On Linux/macOS:
|
||||
sudo dd if=nixos-24.05-x86_64.iso of=/dev/sdX bs=4M status=progress
|
||||
|
||||
# On Windows: Use Rufus or Etcher
|
||||
```
|
||||
|
||||
## Step 2: Boot from USB
|
||||
|
||||
1. Insert the USB drive into your ThinkPad
|
||||
2. Press F12 during boot to access boot menu
|
||||
3. Select the USB drive
|
||||
4. Choose "NixOS Installer" from the boot menu
|
||||
|
||||
## Step 3: Connect to Internet
|
||||
|
||||
### Option A: Ethernet (Easiest)
|
||||
Simply plug in an ethernet cable.
|
||||
|
||||
### Option B: WiFi
|
||||
```bash
|
||||
# List available networks
|
||||
sudo nmcli device wifi list
|
||||
|
||||
# Connect to WiFi
|
||||
sudo nmcli device wifi connect "YOUR_SSID" password "YOUR_PASSWORD"
|
||||
|
||||
# Verify connection
|
||||
ping -c 3 nixos.org
|
||||
```
|
||||
|
||||
## Step 4: Prepare Disk
|
||||
|
||||
### IMPORTANT: Identify Your Disk
|
||||
```bash
|
||||
# List all disks
|
||||
lsblk
|
||||
|
||||
# Your NVMe SSD will likely be /dev/nvme0n1
|
||||
# Verify the size matches your disk
|
||||
```
|
||||
|
||||
### Update Disk Configuration
|
||||
Edit the disk device in your configuration if needed:
|
||||
```bash
|
||||
# If your disk is not /dev/nvme0n1, you'll need to update disk-config.nix
|
||||
# after cloning the repository (see next step)
|
||||
```
|
||||
|
||||
## Step 5: Clone Configuration Repository
|
||||
|
||||
```bash
|
||||
# Install git temporarily
|
||||
nix-shell -p git
|
||||
|
||||
# Clone your configuration
|
||||
git clone https://github.com/Logan-Lin/nix-config.git
|
||||
cd nix-config
|
||||
|
||||
# If needed, update the disk device in hosts/nixos/thinkpad/disk-config.nix
|
||||
nano hosts/nixos/thinkpad/disk-config.nix
|
||||
# Change 'device = "/dev/nvme0n1"' to match your disk
|
||||
```
|
||||
|
||||
## Step 6: Partition Disk with Disko
|
||||
|
||||
```bash
|
||||
# This will ERASE your entire disk!
|
||||
# Make sure you have backups of any important data
|
||||
|
||||
# Partition the disk according to disk-config.nix
|
||||
sudo nix --experimental-features "nix-command flakes" run github:nix-community/disko -- \
|
||||
--mode disko \
|
||||
--flake .#thinkpad
|
||||
```
|
||||
|
||||
## Step 7: Generate Hardware Configuration
|
||||
|
||||
```bash
|
||||
# Generate hardware-configuration.nix
|
||||
sudo nixos-generate-config --show-hardware-config > hosts/nixos/thinkpad/hardware-configuration.nix
|
||||
|
||||
# Review the generated file
|
||||
cat hosts/nixos/thinkpad/hardware-configuration.nix
|
||||
```
|
||||
|
||||
## Step 8: Find GPU Bus IDs
|
||||
|
||||
```bash
|
||||
# Find your GPU bus IDs for NVIDIA PRIME
|
||||
lspci | grep -E 'VGA|3D'
|
||||
|
||||
# You should see something like:
|
||||
# 00:02.0 VGA compatible controller: Intel Corporation ...
|
||||
# 01:00.0 3D controller: NVIDIA Corporation T500 ...
|
||||
|
||||
# Update system.nix with correct bus IDs:
|
||||
nano hosts/nixos/thinkpad/system.nix
|
||||
|
||||
# Find and update these lines with your actual values:
|
||||
# intelBusId = "PCI:0:2:0";
|
||||
# nvidiaBusId = "PCI:1:0:0";
|
||||
```
|
||||
|
||||
## Step 9: Install NixOS
|
||||
|
||||
```bash
|
||||
# Install NixOS using the flake configuration
|
||||
sudo nixos-install --flake .#thinkpad
|
||||
|
||||
# You will be prompted to set the root password
|
||||
# (You can leave it blank since we use SSH keys and sudo)
|
||||
```
|
||||
|
||||
## Step 10: Reboot
|
||||
|
||||
```bash
|
||||
# Remove the USB drive and reboot
|
||||
sudo reboot
|
||||
```
|
||||
|
||||
## Step 11: Post-Installation Setup
|
||||
|
||||
After rebooting into your new NixOS system:
|
||||
|
||||
### Login
|
||||
- Username: `yanlin`
|
||||
- Password: Use the password you know (the hashed one in the config)
|
||||
|
||||
### Apply Home Manager Configuration
|
||||
```bash
|
||||
# Clone the config repo to your home directory
|
||||
cd ~
|
||||
git clone https://github.com/Logan-Lin/nix-config.git .config/nix
|
||||
|
||||
# Apply home-manager configuration
|
||||
home-manager switch --flake ~/.config/nix#yanlin@thinkpad
|
||||
```
|
||||
|
||||
### Verify NVIDIA Setup
|
||||
```bash
|
||||
# Check if NVIDIA driver is loaded
|
||||
lsmod | grep nvidia
|
||||
|
||||
# Test NVIDIA offload
|
||||
nvidia-offload glxgears
|
||||
|
||||
# Check GPU status
|
||||
nvidia-smi
|
||||
```
|
||||
|
||||
### Set Up Power Management
|
||||
```bash
|
||||
# Check TLP status
|
||||
sudo tlp-stat
|
||||
|
||||
# Monitor battery
|
||||
acpi -b
|
||||
|
||||
# Check CPU frequency scaling
|
||||
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### WiFi Not Working
|
||||
- Some ThinkPad models need newer kernel: Already using latest kernel in config
|
||||
- Check if WiFi is blocked: `rfkill list`
|
||||
|
||||
### NVIDIA Issues
|
||||
- If NVIDIA doesn't work, boot with integrated graphics only:
|
||||
- Comment out the nvidia configuration in system.nix
|
||||
- Rebuild: `sudo nixos-rebuild switch --flake ~/.config/nix#thinkpad`
|
||||
|
||||
### Display Manager Not Starting
|
||||
- Switch to TTY (Ctrl+Alt+F2)
|
||||
- Check logs: `journalctl -xeu display-manager`
|
||||
|
||||
### Battery Drain
|
||||
- Ensure TLP is running: `systemctl status tlp`
|
||||
- Check if NVIDIA is always on: `cat /proc/acpi/bbswitch`
|
||||
- Use `powertop` to identify power-hungry processes
|
||||
|
||||
## Useful Commands
|
||||
|
||||
```bash
|
||||
# Rebuild system configuration
|
||||
sudo nixos-rebuild switch --flake ~/.config/nix#thinkpad
|
||||
|
||||
# Rebuild home configuration
|
||||
home-manager switch --flake ~/.config/nix#yanlin@thinkpad
|
||||
|
||||
# Update system
|
||||
nix flake update ~/.config/nix
|
||||
sudo nixos-rebuild switch --flake ~/.config/nix#thinkpad
|
||||
|
||||
# Check system health
|
||||
nixos-option system.stateVersion
|
||||
nix-store --verify --check-contents
|
||||
|
||||
# Clean up old generations
|
||||
sudo nix-collect-garbage -d
|
||||
```
|
||||
|
||||
## KDE Plasma Tips
|
||||
|
||||
- **Global Theme**: System Settings → Appearance → Global Theme
|
||||
- **Display Configuration**: System Settings → Display and Monitor
|
||||
- **Power Management**: System Settings → Power Management
|
||||
- **NVIDIA Settings**: Run `nvidia-settings` from terminal or application menu
|
||||
- **Virtual Desktops**: System Settings → Workspace → Virtual Desktops
|
||||
|
||||
## Running Applications with NVIDIA GPU
|
||||
|
||||
To run applications using the discrete NVIDIA GPU:
|
||||
```bash
|
||||
# Use the nvidia-offload command (alias: nvidia-run)
|
||||
nvidia-offload firefox
|
||||
nvidia-offload steam
|
||||
nvidia-run blender
|
||||
```
|
||||
|
||||
## Notes
|
||||
|
||||
- The configuration includes Firefox add-ons support for the home-manager setup
|
||||
- Claude Code is available after home-manager installation
|
||||
- The system is configured for maximum battery life with TLP
|
||||
- NVIDIA GPU is set to power-saving offload mode by default
|
||||
- KDE Plasma 6 with Wayland support is configured
