i3 Configuration and Everything

Pain, but worth it :) Movinya was here :))

---

0. List of config files (relative to $HOME)

• General i3 configuration file: .config/i3/config`
• Programs configs: (relative to user’s $HOME)

  alacritty # .alacritty.yml
  bash # .bashrc
  zsh # .zshrc
  fish # .config/fish/config
  tmux # .tmux.conf
  neofetch # .config 
  ssh # .ssh/config
  

• Visual themes (folders, rather than config file):

  icons # .icons/ 
  themes # .themes/
  oh-my-bash # .oh-my-bash/
  oh-my-zsh # .oh-my-zsh/
  

  NOTE: .icons/ is also home to themes and cursor themes (default by lxappearence too!)

Natural Scrolling

The default config file for libinput is at /usr/share/X11/xorg.conf.d/40-libinput.conf. Copy it to /etc/X11/xorg.conf.d then edit it your preferred text editor (with sudo)

nvim /etc/X11/xorg.conf.d/40-libinput.conf
...
Section "InputClass"
    Identifier "libinput touchpad catchall"
    ...
    Option "NaturalScrolling" "on" # add this
EndSection
...

Network Configuration (wpa_supplicant & dhcpcd)

• NOTE: recommend using NetworkManager for out-of-the-box experience, but using wpa_supplicant and dhcpcd directly give better control over network management
• Configuration locations:
  • System-wide: /etc/wpa_supplicant/wpa_supplicant.conf
  • User-specific: $HOME/.config/wpa_supplicant.conf
  • Example: /usr/share/wpa_supplicant/wpa_supplicant.conf
• wpa_supplicant.conf configuration: ```yml nvim ~/.config/wpa_supplicant.conf —

  for normal wifi

  Can as well do wpa_passpharse <ssid> <password> > ~/.config/wpa_supplicant.conf to generate the psk

  network={ ssid= psk= }

for education wifi

network={ ssid=”SSID” key_mgmt=WPA-EAP EAP=PEAP phase2=”auth=MSCHAPV2” identity=”USERNAME” password=”PASSWORD” }

- To activate wpa_supplicant: 
```sh
sudo wpa_supplicant -B -i wlan0 -D nl80211 -c ~/.config/wpa_supplicant.conf 

Note: the interface (-i flag) could be something else, e.g. wlo1. You can check it using the following command:

ip addr

• Make sure the interface is up/unblock, using:

  ifstat wlo1 # to check
  ip link set wlo1 up # to unblock interfce
  

• Set wpa_supplicant to run at boot (systemd):
  • Create a service file at /etc/systemd/system/wpa_supplicant@.service:

    # create file
    touch /etc/wpa_supplicant/wpa_supplicant-wlo1.conf
    # copy content
    cat /home/USER/.config/wpa_supplicant.conf > /etc/wpa_supplicant/wpa_supplicant-wlo1.conf
    # enable the service
    systemctl enable wpa_supplicant@wlo1
    

    Note: I expected to enable dhcpcd@wlo1 as well but it seems to be working without it.

Bluetooth Configuration

• Using bluetoothctl, from bluez-utils package. Recommend using blueberry as the GUI interface.

Multiple Displays

• hmm

Clipboard manager
