| # Install ARCH Linux with encrypted file-system and UEFI | |
| # The official installation guide (https://wiki.archlinux.org/index.php/Installation_Guide) contains a more verbose description. | |
| # Download the archiso image from https://www.archlinux.org/ | |
| # Copy to a usb-drive | |

| # OBJECTIVE: Install Arch Linux with encrypted root and swap filesystems and boot from UEFI. | |
| # Note: This method supports both dedicated Arch installs and those who wish to install Arch on a multi-OS-UEFI booting system. | |
| # The official Arch installation guide contains details that you should refer to during this installation process. | |
| # That guide resides at: https://wiki.archlinux.org/index.php/Installation_Guide | |
| # Download the archlinux-*.iso image from https://www.archlinux.org/download/ and its GnuPG signature. | |
| # Use gpg --verify to ensure your archlinux-*.iso is exactly what the Arch developers intended. For example: |
lsusb lists the fingerprint reader in the x240 as follows:
Bus 002 Device 003: ID 138a:0017 Validity Sensors, Inc.

Install fingerprint-gui:
sudo add-apt-repository ppa:fingerprint/fingerprint-gui
