Troubleshooting

Installing i3wm

If your distribution does not packages i3-gaps (check by running sudo apt policy i3-gaps) you can either:

1. Install i3-gaps from source.
2. Install i3 (without gaps) and remove the gaps settings from the config file.
   • sudo apt install i3-wm i3status i3lock
   • cat ~/.config/i3/config-no-gaps.bak > ~/.config/i3/config Once in an i3 super+enter to open a terminal, see the shortcuts here.

Bluetooth pairing

Install dependencies.

sudo apt install blueman
sudo apt install bluez*
sudo apt install pulseaudio pulseaudio-utils pavucontrol pulseaudio-module-bluetooth

Make sure the Bluetooth service is enabled.

sudo systemctl enable bluetooth.service
sudo systemctl start bluetooth.service

Create the config file sudo nano /etc/bluetooth/audio.conf if not exists.

[General]
Enable=Source,Sink,Media,Socket

Then discover available devices and pair the one you need.

bluetoothctl
>> scan on
>> trust <MACADDRESS>
>> pair <MACADDRESS>

Notes

1. home/.homemade is a directory for my custom resources, scrips, etc.
2. Some scrips from home/.homemade/bin might not work properly.
3. To set up the latest color scheme run nohup set-global-color-scheme $HOME/.config/xresources/color-schemes/x-default &>/dev/null && exit.
