Bug ID: 474468
Summary: Power Management auto suspend freezes laptop, but not
Application Launcher Sleep button
Classification: Plasma
Product: Powerdevil
Version: 5.27.7
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: gav...@gmail.com
CC: m...@ratijas.tk, natalie_clar...@yahoo.de
Target Milestone: ---
SUMMARY
I can suspend using `systemctl suspend` and the Sleep button in the Plasma 5
Application Launcher, but I cannot have the Power Management Energy Saving auto
Sleep after an amount of time. The screen goes black except for the mouse
cursor. This also means hybrid-sleep does the same thing. I have to hold the
power button to shut down and restart.
This is the same when setting the laptop lid to Sleep. I cannot test the power
button because it doesn't register when I press it. This may be another issue I
have to investigate.
I don't have this issue with hibernation using all 3 methods. I have also
tested setting the auto option to Shut down, Lock screen and they also work.
I tried looking thru the Powerdevil source code but can't figure out how it's
suspending my laptop and why is it acting different. Anyone know where to look
what the exact command is?
STEPS TO REPRODUCE
1. System Settings > Power Management > Energy Saving > Enable Suspend session
2. Set to automatically Sleep after 5 min
3. Wait 5 min
or
1. System Settings > Power Management > Energy Saving > Button events handling
2. Set laptop lid closed to Sleep
3. Close lid
OBSERVED RESULT
Black screen with cursor visible. Keyboard light stays on.
EXPECTED RESULT
Suspend properly like when using `systemctl suspend` in terminal or pressing
the sleep button in the Application Launcher.
