Fingerprint scanner

Hi guys

I’ve just installed PM4 on my daughters HP Compaq nc4400 laptop and while doing so noticed a strange and intriguing device on the right hand side of the monitor which further investigation has proved to be a fingerprint scanner

So my question is can I make this work in Linux and would this provide the means [How To] Get Your Fingerprint Reader Working in Ubuntu - OMG! Ubuntu

Many thanks

Graeme

I think I may have found the procedure from here https://launchpad.net/~fingerprint/+archive/fingerprint-gui but would appreciate clarification if possible

0. First of all, if you have installed Fingerprint GUI manually before, get rid of it completely. Remove all binaries, shared libraries, any other files and undo all the changes you have made to your system config files (especially to files under /etc/pam.d/).
  1. Add this PPA to your sources:

    sudo add-apt-repository ppa:fingerprint/fingerprint-gui
    sudo apt-get update

  2. Install the packages:

    sudo apt-get install libbsapi policykit-1-fingerprint-gui fingerprint-gui

  3. Log out of your session and log back in (we need the new session defaults to be picked up).

Setup

After installation launch “Fingerprint GUI” and enrol your fingerprints.
That should be all you need to do!
Try locking your screen, logging out and in, sudo in terminal and running graphical apps requiring root privileges.

Fingerprint scanners - preparing your mind for the day when you’re microchipped.

If it were me, it would have been “and then I discovered it was a fingerprint scanner, so I threw the keyboard away, after taking a hammer to it”.

I’m not quite sure what you’re saying there but it’s a nifty wee gadget that I think my daughter would appreciate so if it’s there why not make it work, :slight_smile:

Yup those instructions look OK to me, and that PPA also says your device is supported (08ff:2580)

Ok I.ll give it a go and report back

Thanks

Ok everything installed ok and I can open the gui and save my print scan but I can’t verify it I’ve tried various fingers moving them across the scanner fast & slow light touch hard touch, it will save the print no problem but it just wont verify,

I tried installing aes2501-wy from synaptic and it seems to run ok and finishes with "assembling and prints a print scan but I have no idea what to do from there

laura@lauras-Laptop ~ $ aes2501
argc=1 Initializing, please standby...
aesSetup()...
aesStartScan()...
READY (touch the sensor to stop)

Any help would be much appreciated

What happens if you run:

fingerprint-identifier

?

the swipe icon appears, I swiped the saved finger (not identified) I then pressed enter and it took me back to the command prompt

I earlier followed these instructions under “Authentication” but it still didn’t help Fingerprint GUI - ArchWiki

I don’t know how much I can help with this as I have no way of testing anything … I’ll keep looking, but you may be kinda on your own here.

No problem Mark

Probably best just to un-install Fingerprint GUI, it’s just a gimmick anyway

the only thing worse than something that doesn’t work is something that nearly works :slight_smile:

Anyway thanks for your help

Graeme

Be sure to read your original article again then … it said something about having to reinstall policykit-1-gnome or something.

Ok unfortunately I went ahead and un-installed fingerprint-gui without having first reinstalled policykit-1-gnome and now i cant sudo into anything

any ideas ?

EDIT
I tried installing policykit-1-gnome for the recovery consol and now it wont boot at all so I’ve just decided to reinstall from scratch

Ooops … I’ll bet you won’t be in a hurry to do that again :wink:

At least reinstalling isn’t the chore it is in Windows.

No I wont but what I really need is to learn not to be so impetuous and read things properly (in other words change the habits of a lifetime) that may prove more difficult

All done in around an hour including running updates, installing the programs and configuring everything the way she wants, probably as much as a days work in Windows

Tell me about it … you’re not the only one, I seem to spend half my life digging holes for myself and the other half figuring out how to get out of them … but really I consider that fun :slight_smile:

I also hear you on the time a reinstall takes … reinstalling WIndows is a pull your hair out affair, by comparison reinstalling Linux (the very few times I’ve screwed up that bad I need to) is more of a minor inconvenience … not to mention in Windows you occasionally have to reinstall for no reason other than to get the machine to run quickly again.

People bitch about things like having to reinstall Peppermint annually (if you want the latest version), kinda forgetting they had to reinstall (the same version of) Windows every 6 months if they wanted it to run properly.
