### Backup Disks
Backup disks will respect the following naming convention:
brand_size_purpose_year_month
So for a backup drive you would create:
`wd_4tb_backup_2023_01`
Or for an archive drive:
`samsung_1tb_archive_2023_01`

`smartctl -a /dev/sda`

~~Calibrate with powertop~~
Powertop causes connection issues with USB while the computer is plugged in. Do not
recommend.
```bash
sudo dnf install powertop
# This will take a while
sudo powertop --calibrate
sudo powertop
```
~~Install and enable tlp~~
TLP seems to limit maximum performance. I'm leaving it here for posterity.
Stick with powertop and power profiles daemon.
```bash
sudo systemctl stop power-profiles-daemon.service
sudo systemctl disable power-profiles-daemon.service
sudo systemctl mask power-profiles-daemon.service
sudo dnf install tlp
sudo systemctl mask systemd-rfkill.service
sudo systemctl mask systemd-rfkill.socket
sudo systemctl enable tlp.service --now
sudo systemctl status tlp.service

## Turn Off Fingerprint When Laptop Lid Closed
To disable fingerprint authentication when the laptop lid is closed, and re-enable when it is reopened, we will use acpid to bind to the button/lid.* event to a custom script that will stop and mask the fprintd service on lid close, and unmask and start the fprintd service on lid open.
We also check that the HDMI cable is connected by testing the contents of /sys/class/drm/card0-HDMI-A-1/status.
Follow the steps below:
1. Create a .locks file in your home dir: `mkdir ~/.locks`
1. Create file /etc/acpi/laptop-lid.sh with the following contents:
```bash
#!/bin/bash
lock=/home/ducoterra/.locks/fprint-disabled.lock
if grep -Fq closed /proc/acpi/button/lid/LID0/state # &&
# This is used to detect if a display is connected.
# For USB C displayport use:
# grep -Fxq connected /sys/class/drm/card1-DP-2/status
# For hdmi use:
# grep -Fxq connected /sys/class/drm/card0-HDMI-A-1/status
then
touch "$lock"
systemctl stop fprintd
systemctl mask fprintd
elif [ -f "$lock" ]
then
systemctl unmask fprintd
systemctl start fprintd
rm -f "$lock"
fi
```
2. Make the file executable with
`chmod +x /etc/acpi/laptop-lid.sh`
3. Create file /etc/acpi/events/laptop-lid with the following contents:
```bash
event=button/lid.*
action=/etc/acpi/laptop-lid.sh
```
4. Restart the acpid service with:
`sudo service acpid restart`
Now the fingerprint will be used only when the lid is open.
In order to restore the correct state of the fprintd service if you disconnect/reconnect while the laptop is off, you may call the above script from a systemd init file. The steps to do this are the following:
1. Create a file named /etc/systemd/system/laptop-lid.service with the following contents:
```bash
[Unit]
Description=Laptop Lid
After=suspend.target
[Service]
ExecStart=/etc/acpi/laptop-lid.sh
[Install]
WantedBy=multi-user.target
WantedBy=suspend.target
```
2. Reload the systemd config files with
`sudo systemctl daemon-reload`
3. Start the service with
`sudo systemctl start laptop-lid.service`
4. Enable the service so that it starts automatically on boot
`sudo systemctl enable laptop-lid.service`
Now the status should be correct even after connecting/disconnecting when the computer is off.
