+## 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.

+
+### Autologin
+
+1. Enable autologin from the gnome user settings
+
+### Create an RDP keychain
+
+1. Open "Passwords and Keys" app on the desktop. Password and Keys App
+2. Create a new "Password Keyring" using the "+" icon. Create a new Password Keyring
+3. Name the new keyring "Zero Security Keyring" or something that reminds you it will be un-encrypted. Leave the password blank so that the keychain is unencrypted. You will be warned that you are creating an unencrypted keychain.
+4. Right-click on the new keyring and choose "set as default" Set the new keyring as the default
+5. Click on the old "Default" keyring and delete "GNOME Remote Desktop RDP Credentials" Delete the old RDP password from the "Default keyring"
+6. Open settings and set a new RDP password set a new RDP password
+7. Check that the password was stored under the "Zero Security Keyring" Check that the RDP password was stored in the new keychain
+9. Right click on "Default" keyring and choose "set as default" Remember to set "Default keyring" as the default
