My Dotfiles

This is my dotfiles repository. You can learn more about dotfiles here.

I use Ansible for better flexibility. The main Ansible tasks are located in roles/dotfiles/tasks.

Requirements

# Install ansible and requirements
$ sudo pacman -S ansible
$ ansible-galaxy install -r requirements.yml

Installation

Copy .env.sample to .env and configure environment variables. Then run the playbook:

$ ./install.sh

You can pass ansible-playbook arguments to install.sh:

$ ./install.sh --tags gnome
$ ./install.sh --skip-tags fonts,proxy

You can find the list of tags in roles/dotfiles/tasks/main.yml.

After installing, do not move dotfiles repository. If you did that, install once again.

Manual Configurations

Here I explain some manual configurations that are hard to automate, or I was too lazy to automate!

Wayland

HiDPI + Full HD Monitor Combination in Gnome

If you have multiple monitors (one HiDPI, and one with lower dpi):

1. Use Wayland

2. Enable the experimental fractional scaling feature of Wayland:

   $ gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"
   

3. Open Settings -> Displays, and set Scale to your desired value for each monitor.

HP Printer Setup

$ sudo pacman -S cups
$ sudo systemctl enable --now cups
$ sudo pacman -S hplip
$ sudo hp-setup -i

Map Xiao AI Button

My Xiaomi laptop's keyboard has a button for using Xiao AI in Windows, but it was unusable in Linux. To use this button, I found its scancode (0x72) and mapped it to a linux keycode.

To find the scancode, press the key and look for logs like this in dmesg output:

[ 8474.796476] atkbd serio0: Unknown key pressed (translated set 2, code 0x72 on isa0060/serio0).
[ 8474.796481] atkbd serio0: Use 'setkeycodes 72 <keycode>' to make it known.

Open list of linux keycodes and pick a keycode (e.g. 172: HomePage):

$ cat /usr/include/linux/input-event-codes.h | grep KEY_

One-time mapping

$ sudo setkeycodes 72 172

Permanent mapping

Find your keyboard information with evemu-describe command (evemu package).

Create /usr/lib/udev/hwdb.d/90-redmi.hwdb and set mapping for your keyboard:

evdev:atkbd:dmi:bvn*:bvr*:bd*:svnTIMI:pnRedmiBookPro15:*
  KEYBOARD_KEY_72=172

Update hwdb.bin:

$ sudo systemd-hwdb update

After any change to 90-redmi.hwdb, run sudo touch /usr.

Monospace Fonts

My favorite monospace fonts:

• JetBrains Mono
• Iosevka
• Source Code Pro
• Hasklig
• Cascadia Code

Use a nerd font for better compatibility with shell prompts like Powerlevel10k or Starship. This dotfiles repo installs some nerd fonts.
