SUMMARY
***
After upgrade to Plasma 6, my laptop will not go to sleep. When I ran `systemd-inhibit --list --mode=block`, I get only 1 result:

WHO        UID  USER  PID  COMM            WHAT                                                                       WHY                      MODE 
PowerDevil 1000 elman 6789 org_kde_powerde handle-power-key:handle-suspend-key:handle-hibernate-key:handle-lid-switch KDE handles power events block

Power and Batter widget does not report any app blocking sleep. Manual sleep blocking is off.
***


STEPS TO REPRODUCE
1. No idea. Maybe some problem when upgrading Plasma 5 to Plasma 6?

OBSERVED RESULT
Screen turns off, but after a short while, lock screen is shown.

EXPECTED RESULT
Laptop should go to sleep.

This is an expected result

Can you share the output of `journalctl` command, thanks!

Hi. Thanks for pointing me in the right directions. The issue was with Nvidia drivers and specifically PreserveVideoMemoryAllocations setting. Now sleep on AC works just like before.

I did find crash when trying to wake from sleep on BAT, but I will open new bug for that.

Thanks Aakarsh!
