Open Issues

  • Status as of 2018-07-31: the X1C6 is now supported by fwupd, but in my test with BIOS update 1.27 the firmware is downloaded and noticed by the BIOS at boot but updates don't seem to actually get applied. Alan Orth (talk) 12:17, 31 July 2018 (UTC)

Fingerprint reader

See github.com/nmikhailov/Validity90, especially the 9a branch.

Device id: 06cb:009a

Status as of 04/2018: "Init works, leds work, scan doesn't work yet"

Deep sleep (S3)

Possible solutions:

  • Update of UEFI firmware to allow S3 sleep instead of Si03, i.e. an alternative BIOS for Linux users
  • Making Linux play nicely with Si03, which means:
    • Activating acpi.ec_no_wakeup=1, which sacrifices the functionality of opening the lid to return from suspend
    • Fixing the SD-Card reader to consume less power in Si03
  • Patching the DSDT tables as noted on delta-xi and the forums (potentially dangerous and does not play nicely with BIOS updates)

Other Power saving

Investigate how to get Watt usage down to ~2W like the Dell XPS 13 9360/9370, similar to the instructions on the XPS 9360 page, especially since the i915 video driver can be tweaked similarly with the Intel Graphics Module Powersaving Options since it’s also an HD 620 integrated video unit.
