# `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`)
```sh
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):
```sh
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:
```sh
ip addr
```

- Make sure the interface is up/unblock, using:
```sh
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`:
```sh
# 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
-
