SUMMARY
I'm attempting to put my KDE Wayland session on NVIDIA to sleep. I've tried
three times, but it just keeps waking up! I've tried clicking sleep from the
menu, and I've tried sudo systemctl suspend. No dice.
Here is some of journalctl -r:

STEPS TO REPRODUCE
1. Use Arch Linux with a NVIDIA card, then try to put the desktop to sleep.
Clicking Sleep or running sudo systemctl suspend; it doesn't matter.
OBSERVED RESULT
KDE will wake up within a minute at the display manager.
EXPECTED RESULT
KDE falls asleep until I wake it up again.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 6.5.7-arch1-1 (64-bit)
(available in About System)
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.110.0
Qt Version: 5.15.11
ADDITIONAL INFORMATION
By default, when I resumed a session, the desktop would be completely
corrupted. So I followed the steps here and enabled
nvidia-suspend.service/nvidia-hibernate.service + added options nvidia
NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/tmp/nvprsrv to
/etc/modprobe.d/nvidia-power-management.conf, added it to the FILES array in
mkinitcpio, and regenerated initramfs. After this, suspend worked properly and
when it came back from sleep it worked again. However, it doesn't sleep at all
anymore!
