    * Palette
      * Built-in schemes - `XTerm`
    * Check `Show bold text in bright colors`
* Create a `Profile2` that's a clone of `Profile1`
  * This will be easier to work with when it's important to see everything very clearly

    * Set the background transparency to None

### 🖥️ 🖥️ Dual Monitor Configuration (with display link adapter)

* Disable secure boot in the BIOS

```bash
cd ~/Downloads
git clone https://github.com/AdnanHodzic/displaylink-debian.git
cd displaylink-debian/ && sudo ./displaylink-debian.sh
```

* Deleting this made it start working

```bash
sudo dkms install -m evdi -v 1.14.1
```

* Restart to pick up config changes

```bash
sudo shutdown -r now
```
