The fingerprint reader is not yet supported on 6th gen X1.I never tried to get the LTE modem working. Funnily, I didn't even realize that the slot existed for almost a year after purchase.

I don't know which model of fingerprint reader is in the 6th gen, but on the 7th gen, enabling the beta firmware made it work perfectly.

  $ fwupdmgr enable-remote lvfs-testing

If you temporarily enable, apply the Prometheus fingerprint updates then disable you won't need to worry about installing unstable firmware that will affect the system more widely.

The USB id of the fingerprint reader on X1C6 is 06cb:009a while on X1C7 it is 06cb:00bd.

This is the list of supported devices: https://fprint.freedesktop.org/supported-devices.html

As you can see the one for X1C7 is supported, X1C6 unfortunately isn't.

This is their gitlab issue for it: https://gitlab.freedesktop.org/libfprint/libfprint/issues/13...

I'm getting the following after doing that:

    Firmware metadata has not been updated for 30 days and may not be up to date.

    Update now? (Requires internet connection) [y|N]: y

    Failed to update metadata for lvfs-testing: '48A6D80E4538BAC2' is not a valid signature

Anyone else seen that?

fwupdmgr / LVFS is such a breath of fresh air compared to the various old vendor specific fw update procedures!

The novelty of updating firmware via a GUI on Linux still hasn't worn off.

It works on gen 7 with Ubuntu 20.04. I think it wasn't out of the box though and I needed to do some tweaks

Yeah, the same question about the fingerprint support. There are plenty of decent modern laptops with fine Linux support, except the fingerprint. Well, I'm typing this from my XPS 9575 under Fedora 31 with 5.5 kernel where everything works, except, well, the fingerprint.

Dell solved this problem with their Developer Edition of the XPS13 which they sell with Ubuntu pre-installed: by removing the fingerprint scanner ...

I'm still really happy about that groups work, gotta push further tough.

The fingerprint reader on my T495 works out of the box on the newly released Ubuntu 20.04 and the beta for Fedora 32. It did not on previous versions.

Same here
