My dotfiles

Arch Linux

For faster pacman downloads during the initial bootstrap, uncomment the ParallelDownloads line in /etc/pacman.conf (with =):

sed -i 's/#ParallelDownloads = 5/ParallelDownloads = 5/g' /etc/pacman.conf

(update-system does this automatically afterwards.)

Do a basic install — make sure you include:

base base-devel linux linux-firmware nushell git iptables-nft sudo [amd-ucode|intel-ucode] pipewire neovim efivar efibootmgr networkmanager

Dotfiles Installation

mkdir -p ~/dev
git clone https://github.com/icub3d/dotfiles ~/dev/dotfiles
cd ~/dev/dotfiles
nu install.nu

install.nu symlinks the nushell config and then calls update-system, which installs paru, the packages listed in .selected_packages, and runs the matching packages/post-install/*.nu scripts.

Setup Git

Add this to ~/.gitconfig.local:

[user]
	name = Joshua Marsh (icub3d)
	email = joshua.marshian@gmail.com
	signingkey = [KEY]

If you want GitHub auth (gh is installed via the package manifests):

gh auth login
gh auth setup-git

Syncthing

• Enable syncthing

systemctl enable --now --user syncthing

• http://localhost:8384 > Actions > Show ID

• http://otherhost:8384 > Add Remote Device

• Back on http://localhost:8384 you'll eventually see a request that you can approve and then after a few seconds you'll also see the new shares that you can map.

3rd Monitor Not Working

I kept cycling the power (unplug from monitor) until it finally was recognized?!?!?

Firefox / Bitwarden Lag (Multi-GPU)

If you experience "bursty" typing lag in Firefox or Bitwarden popups on a multi-GPU setup (e.g., AMD + NVIDIA), it is likely due to the compositor trying to sync frames across GPUs.

The Fix: Prioritize the AMD card (connected to monitors) for the Wayland compositor in ~/.config/environment.d/wayland.conf:

WLR_DRM_DEVICES=/dev/dri/card1:/dev/dri/card0

• card1: Primary AMD GPU (7900 XTX)
• card0: Integrated AMD GPU
• Excluded card2: NVIDIA GPU (reserved for AI/CUDA)

GPU Helper Script: Use nu helpers/gpu.nu to check clocks and performance levels. If UI stuttering persists during video playback, you can force the AMD GPU into high-performance mode:

nu -c 'use helpers/gpu.nu; gpu set-perf high'

Docker Slow Stopping

sudo systemctl edit docker and add:

[Unit]
After=containerd.service
Wants=containerd.service
