KDE Sleep Wake Up Security Issue

[venadder]

I am starting to have this issue with KDE X11 lately. My desktop is set to Sleep (Standby) after 30 minutes. When I come back and press power button to wake up it goes straight to desktop with all the windows open when it went to sleep. After a bit of freeze/lag it’s working as normal. I would expect it to go to login screen ( which it used to ) and prompt for password!. System details:

Assuming you booted once after the incident post output of

journalctl -r -b -1

Are you using auto login? What display manager are you using?
Also, please post

pacman -Qm

and

inxi -Fza

Hm I think you mean lock screen here.
What are your settings here (sorry screenshot is from Plasma 5, can add 6 later).

[venadder]

Yeah I meant Lock screen. Here are settings:

I am not using auto login. Detials of issue after trying to replicate it:

1. It seems like it’s actually on lock screen, but on display your desktop from previous session ( hence looks like it is frozen ). It does not actually show you lock screen
   This still is an issue as it’s in plain sight everything I was doing when it went to sleep.
2. It does not happen if I press power button to sleep and then press power to wake up once everything (except RAM ) goes off. It seems to happen when it wakes up after quite a bit of time >15-20 mins

These are not the screen locking settings but for energy saving.
Try searching for “LOCK” in System Settings please.

@Wollie

journalctl -r -b -1

Think it might be the “Allow unlocking without password” setting?

[1efaf7d71a8637c6800a]

If your issue happens with these settings, I’m not able to help further.

@venadder

Think it might be the “Allow unlocking without password” setting?

The 5sec is just right after your 5-minutes timeout.
Does lockscreen show after 5+ minutes ?

[venadder]

So I removed 5 sec ( changed to 0 ) and now it hasn’t happened. Going to observe it a bit more before saying “that solved it”

[1efaf7d71a8637c6800a]

Good idea, I have recently seen screen content also for a blink of an eye before the lockscreen, on both 5 and 6 after wake from hibernate.

It is actually just meant as an, “oops, I don’t want my screen locked right now” when your in front of screen-kind-of-prevention.

Now I am so eloquent am I not

[venadder]

I can confirm removing 5 seconds ( changing to 0 ) fixes

1. Desktop displayed
2. Screen freeze

It actually now goes right away to lock screen and is responsive
