DEPRECATED

I have been using Arch Linux since 2020, while still using Nix for side projects. I still think Nix is the only sensible way to manage software today. I will come back to NixOS soon..

First, you need to install a fresh NixOS following the manual.

Then, you need to have git on the system. If installing is required do nix-env -iA pkgs.git. You will need to import your github private key (or create a new one ssh-keygen -t rsa -b 4096 -C "[email protected]") and it to openSSH daemon ssh-add /home/arnau/.ssh/github.

# ! Backup your /etc/nixos/hardware-configuration.nix

$ sudo rm -r /etc/nixos
$ sudo git clone [email protected]:monadplus/nixconfig.git /etc/nixos

Before realising your configuration you must add (test if you really need it) home-manager channels:

$ nix-channel --add https://github.com/rycee/home-manager/archive/release-XX.XX.tar.gz home-manager
$ nix-channel --update

To install everything:

# This will take a long time (about 10-20')
$ sudo nixos-rebuild switch
$ reboot

Command-lines

Terminal emulator

• Konsole: my personal choice.
• Alacritty: I couldn't manage to configure very basic shortcuts like clear history.

Monitors

Just plug your screen and run autorandr -c

arandr is the graphical version of xrandr (use this one.)

xrandr (cli):

xrandr # List monitors and options
xrandr --auto # Detect monitors and connect them
xrandr --output HDMI-1 --off # Disable hdmi monitor
xrandr --output HDMI-1 --right-of eDP-1  # Place HDMI-1 at the right
# ^^^^^^ To change mirror monitoring

We installed autoxrandr to change config when hardware changes.

It requires a bit of configuration to automatically work ! (read https://github.com/phillipberndt/autorandr#how-to-use)

On home.nix we set up a declarative autorandx.

Wi-fi

Known networks are set on configuration.nix

wpa_gui: GUI, simple to use.

wpa_cli:

$ wpa_cli
> scan
OK
<3>CTRL-EVENT-SCAN-RESULTS
> scan_results
bssid / frequency / signal level / flags / ssid
00:00:00:00:00:00 2462 -49 [WPA2-PSK-CCMP][ESS] MYSSID
11:11:11:11:11:11 2437 -64 [WPA2-PSK-CCMP][ESS] ANOTHERSSID

# If the SSID does not have password authentication, you must explicitly configure the network as keyless by replacing the command

> save_config
OK
> quit

Audio

alsamixer

We set up keybinding to automatically increase/decrease the volume.

The volume for the bluetooth headsets doesn't work.

Bluetooth

blueman-manager (gui) / blueman-applet (daemon)

Command line:

$ bluetoothctl
[bluetooth] # power on
[bluetooth] # agent on
[bluetooth] # default-agent
[bluetooth] # scan on
...put device in pairing mode and wait [hex-address] to appear here...
[bluetooth] # pair [hex-address]
[bluetooth] # connect [hex-address]

pavucontrol to manage bluetooth devices configuration.

Disk managers

Partitions: $ parted

To display partitions: $ sudo parted -l

Disk space usage analyzer: $ ncdu

VPN

$ openvpn

Touchpad

Touchpad configuration is managed by libinput.

The configuration is managed in a declarative way.

How to change the sensivity:

$ xinput list # Search for TouchPad id
$ xinput --list-props ID # From the previous list
$ xinput --set-prop ID "libinput Accel Speed" 0.3 # 0.3 is just an example

Managed by scrot.

Hotkeys:

• PtrSc
• Ctrl + PtrSc

Clibpard manager

clipmenu

Requires a systemd daemon runnning: clipmenud

And then you can access the tray: https://github.com/cdown/clipmenu

I remapped clipmenu to Ctrl+Shift+V via xmonad.

$ nomacs <<image.jpg>>

Translate CLI

We use translate-shell for that:

trans -s es -t en   word | multiple words | "this is a sentence."

translate-shell is configured via the dotfile ~/.translate-shell/init.trans.

BitTorrent

Open transmission at http://localhost:9091/transmission/web/

Open it via transgui.

Transmission daemon can be controlled via the RPC interface using transmission-remote or the WebUI (http://localhost:9091/ by default).

Xmonad

Xmonad configuration can be found at ./dotfiles/xmonad/xmonad.hs and it's configured via nixos (i.e. there is no need to symlink it to ~/.xmonad/).

xmonad top bar is a plug-in called xmobar and it is configured with it own config file: ~/.xmobarrc (can be found on ./dotfiles/xmonad/.xmobarrc)

GPG

Files protected with GPG have the extension .gpg. In order to encrypt/decrypt them:

# Encrypt
gpg -c filename

# Decrypt
gpg filename.gpg
