Need help with setting up the fingerprinter reader for my laptop. I ran lsusb but nothing is coming up?

Some information about that some models will be supported in the 4.20 kernel
https://www.phoronix.com/scan.php?page=news_item&px=LG-Gram-Laptop-Linux-Driver

The arch wiki on using the Fingerprint GUI
https://wiki.archlinux.org/index.php/Fingerprint_GUI

A link to the AUR package is in the wiki. If you want to install it on Manjaro you will need to:

  • Install the 4.20 kernel using the Manjaro Settings Manager > Kernel
  • Then from terminal run
    sudo pacman -S trizen base-devel --needed
    trizen -S fingerprint-gui --noconfirm

thanks, I think I have the 4.20 running on my lg gram I will give it a go


#4

please advice how to run the command in the right order. if enter at once, getting “error only one command can be used at time”. The finger-gui most be installed first i take it?


#5

Each line separately, after the first finished run the second.


#6

thanks, all installed now. Do i then just run fingerprint-gui in the command line?


#7

No :slight_smile: You have to follow the entire wiki i provided about it, check each step and do what they suggest there.


#8

thanks, just ran the first step listed on the wiki and reached a wall. No finger print device found. I guess the drivers and hardware from LG is not fully implemented on in the new kernel.


#9

you may wish to ask philm nicely to take a look at this. the person compiling the kernel has to enable the new LG Gram hardware support according to the phoronix article. it is only available if a flag is toggled during the kernel build.

toggled at build time via LG_LAPTOP Kconfig switch

#11

#14

Let’s see the xinput --list if is listed there, then it should work …


#15

is this a command line list, how do I use it.


#16

Open terminal an run it from there, then share that list it displays.


#17

getting this error “bash: Xinput: command not found”


#18

is xinput not Xinput but maybe is unrelated to case-sensitive and you need to install it:
sudo pacman -S xorg-xinput
then
xinput --list

I think this is it, but i can’t find any references about it. You will have to wait that someone with more knowledge comes along, as i can’t help you out.
