SUMMARY
After Update to  Plasma 6.5 the Stendby did no work, even if you use the standby button. This is was fixed for me on the version 6.5.1. Right now my problem is that the option standby on closed lid dose not work. 

Plasma locks the user out and the screen is of, but the device is still running normaly

STEPS TO REPRODUCE
1. Have standby on closed lid before the update
2. Update from Plasma 6.4 to 6.5.2
3. Test with a laptop and see if closing the lid and executing standby works

OBSERVED RESULT
Device is still running but the user is locked like expected.

EXPECTED RESULT
Standby on closed lid

I'm not able to reproduce this on a laptop running Plasma built from git-master. The system goes to sleep both with the power button (configured to trigger sleep) and by closing the lid.

Can you gather some system logs and attach them as a text file to this report? 
First, trigger the bug and log back in. Then, run this in a terminal:

sudo journalctl  --since "2min ago" > ~/log.txt

And attach ~/log.txt to this report.
Also, what is the output of

cat /proc/acpi/wakeup | grep enabled

Thanks.

Created attachment 186796 [details]
output from "sudo journalctl  --since "2min ago" > ~/log.txt"

Waking the device up from sleep, closing the lid and open it again shortly after.
Screen was off, so i closed the lid again and waited some seconds, opened the lid up ageing and the login prompt is shown.

Wakeup output is:

GLAN	 S4	*enabled   pci:0000:00:1f.6
XHC	 S3	*enabled   pci:0000:00:14.0
RP09	 S4	*enabled   pci:0000:00:1d.0
RP13	 S4	*enabled   pci:0000:00:1d.4
SLPB	 S3	*enabled   platform:PNP0C0E:00
LID	 S4	*enabled   platform:PNP0C0D:00


Is there something i can have a look my self?
For me it looks the event for the lid event is regeisterd and sleep/supsend is engeage but somhow it wakes up again?
I do not like the "Stopped target Sleep." 
And then the NetworkManager dose some stuff while the lid is closed...

Thanks for the logs. Those more familiar with this will have to take a look from here.
