Bug ID: 413387
Summary: Unable to unlock after wake up
Product: kscreenlocker
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: greeter

SUMMARY
Hi everyone,
I have a strange behavior when my laptop wake up from sleep mode. Like this bug
https://bugs.kde.org/show_bug.cgi?id=329076, the widget to enter the password
and then unlock the screen is missing, so I am unable to unlock. The clock is
visible (but not updated, the time is at when I put the laptop to sleep), the
login background too.
The mouse is moving, and the computer does not seem freezed, I can switch
between tty, but the widget ket missing. This a quite strange as the bug does
not occurs every time. Just a few once...
My laptop is a Dell E7470 with latest KDE Neon (KDE 5.17 et Ubuntu 18.04,
built-in Intel HD graphics), with an extra screen (which I think that might
cause the issue). Note that the bug does happens in my desktop computer (with
nVidia graphics card) or my second laptop (Lenovo with graphics card too).
STEPS TO REPRODUCE
1. Close the laptop to go in sleep mode
2. Open the laptop to wake up
3. The login widget is missing (sometimes)
OBSERVED RESULT
The widget to enter the password in order to unlock the computer desktop is
missing.
EXPECTED RESULT
I must be able to see the password widget every time.
