I recently installed DHH’s Omarchy (an Arch Linux distribution based on the Hyprland desktop environment) on my home computer.

After installation, there were a few configuration tweaks I needed to make. I’m recording them in this post for reference.

4K Monitor Settings

Modify the system menu Setup - Monitor, and set the parameters based on your own display’s resolution, following the comments in the configuration file. For example, my 27-inch 4K display:

env = GDK_SCALE,1.75
monitor=,preferred,auto,1.875

Add additional scaling settings for QT applications:

env = QT_AUTO_SCREEN_SCALE_FACTOR,1
env = QT_SCALE_FACTOR,1.75

Chinese Input Method

Refer to Fcitx Best Configuration Practices. The section titled “Installing emacs-rime” in that article can be skipped if you don’t use emacs.

Terminal Font Settings

The default system fonts aren’t very friendly to Chinese in the terminal. I like the Maple Mono font, which you can install via the AUR package maple-mono-nf-cn. Then modify the font settings in ~/.config/alacritty/alacritty.toml:

[font]
normal = { family = "Maple Mono NF CN" }
bold = { family = "Maple Mono NF CN" }
italic = { family = "Maple Mono NF CN" }
size = 12

Disable NumLock by Default

Omarchy enables NumLock on the numpad by default after installation. You can change this in the system menu Setup - Input:

numlock_by_default = false

A Few Neovim Settings

Neovim uses Lazyvim by default. I added a few lines to ~/.config/nvim/lua/config/options.lua—feel free to pick what you need based on the comments:

-- Fix the issue of Chinese characters showing underlines in the terminal
vim.opt.spelllang = { "en", "cjk" }

-- Disable syntax checking in markdown files
vim.api.nvim_create_autocmd("FileType", {
 pattern = "markdown",
 callback = function()
  vim.diagnostic.enable(false)
 end,
})

Then create ~/.config/nvim/lua/plugins/flush.lua with the following content to restore Vim’s default behavior for the s key in normal mode:

return {
  {
    "folke/flash.nvim",
    keys = {
      { "s", mode = { "n", "x", "o" }, false },
    },
  },
}
