I am using Ubuntu 19.10 in Asus X510UN. Using the lsusb command I can't find Fingerprint Device, and it's even showing no device found in fprintd-enroll.
I have built-in fingerprint reader in my touchpad.

Is your device on this list? https://fprint.freedesktop.org/supported-devices.html
I see a lot of elantech devices on the list that are fprintd-enroll supported.
Other options instead of fprint look like fingerprint-gui https://launchpad.net/~fingerprint/+archive/ubuntu/fingerprint-gui
Which supports these devices: https://fprint.freedesktop.org/supported-devices.html
Or thinkfinger which is only think pads: http://www.thinkwiki.org/wiki/Integrated_Fingerprint_Reader#Software_support
I have a Lenovo L380 and am still looking for a package that supports my Synaptics fingerprint reader. I'm kind of a newbie myself so I'm still learning things but that is where I would start looking.
My Ubuntu not Even Showing that there is fingerprint reader in my Laptop... When i use lsusb in terminal it only shows about USB and other devices but Not Fingerprint.
As Lucas suggests, check if your device is supported. If not, it might be under development at the fprintd project. You kernel might not show a fingerprint device, you could try a newer kernel to see if there is a difference.
To identify your device, check for any device ID in the lsusb output that has no name behind it.
Mine shows: Bus 001 Device 003: ID 27c6:538c Shenzhen Goodix Technology Co.,Ltd. Fingerprint Reader
It's showing the device but it does't work in fprintd-enroll either because no driver is loaded. If your device starts with 27c6 it's likely a Goodix too.
Check with that at the project page if a driver might be under development: https://gitlab.freedesktop.org/libfprint/libfprint/issues?scope=all&utf8=%E2%9C%93&state=opened&search=27c6 and if possible try to help out in any way.
With a bit of luck a driver may be coming from Dell, but that's not certain. A Goodix device is apparently in the Dell Precision 5530 and they support Linux on it, but it might be the model without that ( like in previous versions).
This suggests: https://certification.ubuntu.com/catalog/component/27c6:538c for example for this one: https://certification.ubuntu.com/hardware/201807-26295 that the mentioned fingerprint reader is supported by the 4.15 oem kernel.
You could try to build it from: https://code.launchpad.net/~canonical-kernel/ubuntu/+source/linux-oem/+git/bionic/+ref/oem or add the Dell repo to find the Dell shipped oem kernel.
I hope that helps!
Update 2020
If you need an official package, Upgrade to ubuntu 20.10, Fingerprint is now supported in the latest version Here
