Description Ronnie Bailey 2022-06-04 03:58:12 UTC

SUMMARY
The summary states the problem. If I use hot keys to lock the screen, I get the error. However if I click on kscreenlocker_greeter from Dolphin, it works normally. dmesg gives me the following, with the second line repeated many times: 
Lockdown: X: raw io port access is restricted; see man kernel_lockdown.7
Lockdown: systemd-logind: hibernation is restricted; see man kernel_lockdown.7

OS is openSUSE 15.3, using their newer KDE repos. I use X11 and do not have Wayland installed. KERNAL_LOCKDOWN is a new kernel feature, but I am not sure why it would prevent locking from hot keys, but allow it by opening the greeter with a mouse click. 

STEPS TO REPRODUCE
1. Use the hot keys to initiate the screenlocker
2. 
3. 

OBSERVED RESULT
Given a SDDM screen stating that the screenlocker is broken and instructions on how to unlock with a virtual terminal

EXPECTED RESULT
I expect to have the lockscreen presented after using the hot keys

This was broken in the beta, but fixed since then, and will be fixed in the final 5.25 release. Thanks for testing!

Thank you for the info. Since openSUSE doesn't list these as unstable or testing, I had no idea. They are actually listed as stable, with unstable or testing packages at different URLs. Hopefully the 5.25 packages will be available soon in those repos.

Comment 3 Ronnie Bailey 2022-06-14 23:32:25 UTC

I upgraded all KDE and Plasma packages today. I can confirm that this bug still exists in kscreenlocker-5.25 as I now have 5 broken machines.

Is it better now with 5.26 and newer openSUSE packages? Nobody else has been reporting this, so I'm wondering if it's weird interaction between your repos' software.

Yes. Apologies for not reporting earlier.
