Dotfiles and scripts

Dotfiles for macOS and Linux.

Installing Arch

Run archinstall in the live CD. I choose the i3 preset.

When prompted, I use this list of starter packages:

vim tmux htop firefox wpa_supplicant man-db networkmanager network-manager-applet dex xss-lock git

On my 2013 MacBook Air, I also get broadcom-wl for wireless drivers.

Installing dotfiles and programs

Enable multilib packages:

$ sudo vim /etc/pacman.conf
[multilib]
Include = /etc/pacman.d/mirrorlist
$ sudo pacman -Syu

Install yay:

$ git clone https://aur.archlinux.org/yay-bin.git
$ cd yay-bin
$ makepkg -si

Install st:

$ git clone https://github.com/tvararu/st.git
$ cd st
$ sudo make install
$ yay -S libxft-bgra

Install dmenu:

$ git clone https://github.com/tvararu/dmenu.git
$ cd dmenu
$ make
$ sudo make install

Install i3status:

$ yay -S autoconf libconfuse-dev libyajl-dev libasound2-dev libiw-dev \
  asciidoc libpulse-dev libnl-genl-3-dev meson
$ git clone https://github.com/tvararu/i3status.git
$ cd i3status
$ mkdir build
$ cd build
$ meson ..
$ ninja
$ sudo ninja install

Install fish:

$ yay -S fish
$ chsh -s $(which fish)
$ fish
$ rm -r .bash*

Then:

$ cd
$ git clone https://github.com/tvararu/.dotfiles.git
$ mkdir .ssh .vim .gnupg
$ mkdir -p .local/share .local/bin
$ touch .Xresources.local
$ cd .dotfiles
$ ./arch.sh
$ stow --adopt */  # Replaces all existing dotfiles with symlinks to this repo
$ git reset --hard # Updates local dotfiles to be the same as in this repo
$ stow --restow --ignore=".theme.*" */ # Installs remaining dotfiles

macOS setup

$ ./macos.sh

System-specific configuration

Wifi (MacBook Air)

After first-booting on my laptop:

$ sudo modprobe wl
$ sudo systemctl enable --now NetworkManager.service
$ nmtui

Mounting an SD card

$ mkdir /mnt/SD
$ sudo vim /etc/fstab
UUID=<get using blkid>  /mnt/SD exfat defaults,uid=1000 0 2

Syncthing

$ sudo systemctl enable --now syncthing@$USER.service
$ open http://127.0.0.1:8384

Screen brightness

$ yay -S acpilight
$ sudo gpasswd -a $USER video

Screen tearing

Firefox and other apps tear the screen when scrolling or otherwise changing large sections of the screen. Bumping the refresh rate from the default 60Hz and enabling FreeSync fixes it:

$ xrandr --rate 100
$ xrandr --output DisplayPort-0 --set TearFree on

To persist past restart:

$ cvt 3440 1440 100.00 # Generate modeline
$ xrandr --verbose -q  # Or extract it like this
$ sudo vim /etc/X11/xorg.conf.d/10-monitor.conf
Section "Device"
  Identifier "AMD"
  Driver     "amdgpu"
  Option     "TearFree" "true"
  Option     "VariableRefresh" "true"
EndSection

Section "Monitor"
  Identifier "DisplayPort-0"
  Option     "Primary" "true"
  Modeline   "3440x1440_100.00"  543.50  3440 3488 3552 3600  1440 1443 1453 1510 -hsync +vsync
  Option     "PreferredMode" "3440x1440_100.00"
EndSection

Bluetooth

Auto power-on after boot:

$ sudo vim /etc/bluetooth/main.conf # Scroll to end
[Policy]
AutoEnable=true
$ sudo systemctl enable --now bluetooth.service

Use bluetoothctl to detect, pair, trust, and connect to peripherals:

$ bluetoothctl
> power on
> paired-devices
Device 04:4B:ED:E4:56:A2 Theodor’s Keyboard
Device DA:3C:8B:06:59:70 MX Master
> scan on
> trust <mac>
> pair <mac>
> connect <mac>

When connecting to the Apple keyboard, you need to type in a pairing code. Without a second keyboard, you can use onboard as an on-screen keyboard.

Mouse configuration

After installing logiops-git:

$ sudo vim /etc/logid.cfg
devices: ({
  name: "Wireless Mouse MX Master";
  hiresscroll: { hires: true; invert: true; target: false; };
});
$ systemctl enable --now logid.service

Keyboard

To change the overall keyboard layout to the one for an Apple ISO UK keyboard:

$ sudo localectl --no-convert set-x11-keymap gb apple mac

transmission-daemon

Use the system user instead of transmission:

$ sudo systemctl edit transmission.service
[Service]
User=deity

To start now and on startup:

$ sudo systemctl enable --now transmission.service

auto-cpufreq

$ sudo systemctl enable --now auto-cpufreq

Set timezone when connecting to a network

To automatically set the correct timezone when connecting to a new network:

$ sudo vim /etc/NetworkManager/dispatcher.d/09-timezone
#!/bin/sh
case "$2" in
    up)
        timedatectl set-timezone "$(curl --fail https://ipapi.co/timezone)"
    ;;
esac

Don't lock sudo for 10 minutes if wrong password is provided

$ sudo vim /etc/security/faillock.conf
deny = 100

Make screen blank/turn off after 1 hour

$ sudo vim /etc/X11/xorg.conf.d/10-monitor.conf
Section "ServerFlags"
  Option "StandbyTime" "60"
  Option "SuspendTime" "60"
  Option "OffTime" "60"
  Option "BlankTime" "60"
EndSection

GUI scaling

$ echo "Xft.dpi:       192" >> .Xresources.local
$ echo "*.font: monospace:size=11" >> .Xresources.local

Fingerprint reader

Restrict enrolling to the current user:

polkit.addRule(function (action, subject) {
  if (action.id == "net.reactivated.fprint.device.enroll") {
    return subject.user == "deity" ? polkit.Result.YES : polkit.Result.NO
  }
})

Enroll the finger:

$ fprintd-enroll deity

Modify /etc/pam.d/{system-local-login,lightdm,sudo,i3lock} by adding this at the top:

auth		sufficient  	pam_unix.so try_first_pass likeauth nullok
auth		sufficient  	pam_fprintd.so

Pausing media playback when unplugging headphones

$ sudo vim /etc/acpi/events/stop-music-when-headphones-unplug
event=jack/headphone HEADPHONE unplug
action=su - USER -c "env DISPLAY=:0 DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus playerctl pause"
$ sudo systemctl enable --now acpid
