On new installation of EOS, using Thinkpad W541 with NVIDIA disabled, KDE Plasma/Wayland.
Installed with the hibernate option for swap partition, then set everything to sleep then hibernate. When I close the lid, the laptop goes to sleep, but will not hibernate after a length of time.
I can do systemctl hibernate successfully.
Looking at journalctl, every hour I have similar events listed below:
