Bug ID: 476567
Summary: Moving the mouse within the screen lock grace period
breaks the locker in some cases
Classification: Plasma
Product: kscreenlocker
Version: git-master
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: putr...@gmail.com
Target Milestone: ---
SUMMARY
With a Plasma 6 session compiled using kdesrc-build, if the screen locks
automatically but I move the mouse within the "Allow unlocking within password"
time period the screen will either freeze after unlocking or just go black, and
when that happens I have to use the `loginctl unlock-session` command from
another TTY.
So far it appears that the screen locker only does that after I've locked the
session manually and/or I've suspended the system at least once, the problem
doesn't occur on a fresh reboot. The problem also doesn't occur if I move the
mouse after the grace period, and disabling that grace period completely also
works around the problem.
STEPS TO REPRODUCE
1. Set up the system to lock automatically after 1 minute and allow unlocking
without a password for 10 seconds (optional for easier testing)
2. Wait until the screen locks automatically
3. Move the mouse within 10 seconds (or under whatever time is set for the
unlock without password setting)
OBSERVED RESULT
The screen is not properly unlocked, and the session is inaccessible without
using the `loginctl unlock-session` command.
EXPECTED RESULT
The screen should unlock without asking for a password.
