edited January 23 in Swift and Spin Series

My device (swift go) has 10a5-e340 which is a random sensor but common in acer laptops.

I have tried with u ubuntu fedora in both case it did not work my basic debugging told me that this one is not supported in libfprint kindly provide a patch asap so o can use it on my laptop with Linux thanks...

Windows does offer the flexibility that I need. In my workflow i have mac m2 pro and 1 Linux system so I can't use windows…

    We need to know for sure which Swift Go model you have, there have been a bunch of them over the years. Your full model number is usually on the same sticker as your serial number, it should look something like SFGxx-xxx-xxxx.Usually it takes a year or so for the Linux developers to bake in drivers to the kernel for new laptop designs.

    SFG14-41.

    Which is a ryzen7 acer swift go laptop.

    Linux developers are mostly from brands like lenovo have there own to support there devices and upstream it.

    For dell case is same if acer took a senior which is too rare and does not support libfprintd they means acer should provide the patch to libfprintd which is notthat hard at all.

    Even acer does not have basic fwupd lvfs to update firmware and bios this is really bad.

    Windows 11 is really a bad os with ui to stability just on cold boot it use 4.5 ram with fedora i full gnome ui i could open gimp libre office 4 videos play and one page normal website still i was 4.3gb i have tested..

    My request is please provide support

    https://fprint.freedesktop.org/

    Which is east one dev for 7days max he or she can provide finger print support in fprint.

    And fwupd is the most efficient way of delivering firmware i really don't know why acer is not a part of it.

    Just look at the other brands

    OK, Acer used a few different sensors on those models, though the differences between them are sometimes only colors.

    If you look on the support site, they have separate Windows drivers for the Elantec and Carewe sensors, so there are hardware differences between the two. Worse comes to worst you could always switch versions on your system. I'd expect the Elantec to have better driver support for odd OS versions like Linux. It looks like Carewe has a patent on the 'fingerprint sensor in a keycap' technology, but they seem to be a design house in Taipei, so may be fairly small.

    Acer doesn't ship those models anywhere in the world with Linux installed, that I know of. If they shipped with a Linux flavor they would provide Linux drivers…

    if that is the case provide a fix to reduce ram usage from 30% which is 5000mb on cold boot to a 1.5gb which i get from linux distros thanks such as fedora or ubuntu.

    but if users want to use linux it is acers duty to provide adequate drivers i want a driver for my finger print reader for fprint linux.

    You need to be in contact with the Linux developers for your flavor, they are the ones who will provide any needed OS drivers.

    Just on a cold boot it is using 4gb of ram on my ubuntu/fedora it is 1.1gb of ram.

    So on my linux system i can run. 14b parameter model where as if you run that on windows my windows system will stop working.

    Patch windows so it does not need that much ram.

    Same on my mac mini m2 it use 1.6gb ram on a cold boot.

    I want to know what windows does on a cold boot that it need that much ram or windows is a bad os by itself.

    you can use Resource Monitor to see every task and how much memory is allocated to that task, both in use amounts and set aside amounts…

    that is the problem with close stuff

    please provide linux firmware for finger print

    As we have stated several times, you need to look to the Linux developers for drivers. Acer doesn't support Linux on these systems so doesn't develop drivers for that OS.

    why not have you asked acer why they dont want to support.

  • billsey
    billsey ACE Posts: 35,601 Trailblazer

    You should be asking Acer these questions, since you are the user who wants to have it supported by Acer. We are all just other Acer users and very few of us are running Linux, especially with the newest hardware.

    Are you not from the acer team I thought you are from acer

  • billsey
    billsey ACE Posts: 35,601 Trailblazer

    No, we are all just Acer users here. Some of us who have a good track record are given access to things like service guides, but we have no direct conduit to anyone there other than the moderators, and they are mostly concerned with the user interface in these forums and things like proper conduct and spam filtering.
