Bug Description
Issue: Fingerprint identification not working when system is idle without screen going blank
Setup
System prerequisite: FP enrolled on system, Identify works fine.
OS: Verified on: 20.04 PPA release.
Steps to reproduce:
• Now lock the user again. Select the User.
• Leave the laptop idle for 30sec, swipe mouse across and don’t allow the system to go for sleep for 30 seconds. Place the enrolled FP on reader post 30 seconds.
• Observe that FP doesn't get detected at login screen.
• Need to enter password to login into user account.
• Note: "Swipe finger" option at login screen is still shown even if FP doesn't get detected
Attached the fprintd debug log.
Events actions are mentioned with this symbol <==> at attached output.
<==> Some timeout is observed and after this Host is releasing the device and Identification is working only after hitting Enter key to start identification process, timeout is not generated from FW and FW is ready to accept the finger swipe.
