Does not appear to work at the moment.

The class is "Application Specific Interface" and interface is "Broadcom USH w/touch sensor". In the listing above its Bus 001 Device 005: ID 0a5c:5834 Broadcom Corp.

As of this writing, the device is listed on libfrint's [[https://gitlab.freedesktop.org/libfprint/wiki/-/wikis/Unsupported-Devices|Unsupported devices]] list and there is a [[https://gitlab.freedesktop.org/libfprint/libfprint/-/issues/88|related ticket]] requesting its inclusion.

The card reader component is documented in the next section.
Line 102: Line 111:
pcsc-tools contains pcsc_scan which can be used to monitor the cards. While I don't have a functioning smart card to test with it has detected other things like a credit card once inserted. The internal card reader should more or less Just Work - pcsc-tools contains pcsc_scan which can be used to monitor the cards.

While I don't have a functioning smart card to test with it has detected other things like a credit card once inserted.

To enable the NFC wireless smartcard reader requires running a magic script available [[https://github.com/jacekkow/controlvault2-nfc-enable|on GitHub]] to try and enable support using packet captures fed back to the device.

The script worked enough for me to detect a bank card and various public transport/library cards, but not enough to read a Yubikey.

DebianOn is an effort to document how to install, configure and use Debian on some specific hardware. Therefore potential buyers would know if that hardware is supported and owners would know how get the best out of that hardware.

The purpose is not to duplicate the Debian Official Documentation, but to document how to install Debian on some specific hardware.

If you need help to get Debian running on your hardware, please have a look at our user support channels where you may find specific channels (mailing list, IRC channel) dedicated to certain types of hardware.

The PC is well recognized on Debian Stretch and Buster (Early 2019).

Important Note

BIOS Settings

You have to change some BIOS settings before you can install Debian. Press F12 again when starting your notebook to get into the BIOS.

  • System Configuration: SATA Operation: change "RAID On" to "AHCI". Without this change, Linux won't find the internal hard disk.
  • Secure Boot: Secure Boot Enable: change to "disabled" since Debian currently doesn't support secure boot. (NOTE: This requires new testing. Buster DOES support secure boot and similar models of computer (eg Dell 5400) will install with it).
  • ?I had to manually create a boot record under General -> Boot Sequence - adding a boot option pointed at EFI/debian/grub64.efi was enough. I'm not sure how widespread this issue might be or if its due to me turning off SecureBoot (an act which is no longer required with recent installers).

Configuration

Display

  • (not covered yet)

Intel video, works out of the box.

suggests using i915 firmware.

Touch screen works as a pointing device

Audio

Works out of the box.

Mouse

works out of the box, touchpad, trackball, screen and external device

Power Management

suspend works, hibernate untested.

WiFi/Bluetooth

  • Requires the non-free package iwlwifi:

apt install firmware-iwlwifi

Fingerprint reader

Does not appear to work at the moment.

The class is "Application Specific Interface" and interface is "Broadcom USH w/touch sensor". In the listing above its Bus 001 Device 005: ID 0a5c:5834 Broadcom Corp.

As of this writing, the device is listed on libfrint's Unsupported devices list and there is a related ticket requesting its inclusion.

The card reader component is documented in the next section.

Smart card reader

Comes with internal (contacted) card reader and wireless card reader options.

The internal card reader should more or less Just Work - pcsc-tools contains pcsc_scan which can be used to monitor the cards.

While I don't have a functioning smart card to test with it has detected other things like a credit card once inserted.

To enable the NFC wireless smartcard reader requires running a magic script available on GitHub to try and enable support using packet captures fed back to the device.

The script worked enough for me to detect a bank card and various public transport/library cards, but not enough to read a Yubikey.
