Options missing from Power Management in System Settings

[brucehankins]

Hey All,
I recently installed Kubuntu 23.10 (fresh install from 23.04) and I'm missing the Hybrid-Sleep and Hibernate functions in the Power Management in the system settings menu. I had this previously in 23.04 and have had it on every other distro I've ran with Plasma.
installed using LVM and the first thing I did was reboot directly into the live .iso and increase my swap size. My laptop has 12 gb of ram, so I increased my swap to 17.5 gb, then did my first boot into the fresh install. I've checked and modified /etc/systemd/sleep.conf to allow for hybrid-sleep and hibernate, but they still do not show up in the menu. Do I have to rebuild grub first? Am I missing some step with systemctl?
Any help is appreciated, I've also listed out my lsblk below so you can see how the volumes are structured.

nvme0n1 259:0 0 238.5G 0 disk
├─nvme0n1p1 259:1 0 512M 0 part /boot/efi
└─nvme0n1p2 259:2 0 238G 0 part

└─vgkubuntu-swap_1 252:1 0 17.5G 0 lvm [SWAP]

Welcome.

So what do sudo systemctl status hibernate.target and sudo systemctl status hybrid-sleep.target say?

PS:
You might have to rebuild your initramfs …
And if during update-grub the wrong resume partition is set, one can define it with e.g. the swap's UUID in /etc/initramfs-tools/conf.d/resume .

Here is the output.

And here is grub config

GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=3
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=f347bc2f-207a-450e-ba9e-9033a93b815d"
GRUB_CMDLINE_LINUX=""

Here is /etc/systemd/sleep.conf
AllowSuspend=yes
AllowHibernation=yes
AllowSuspendThenHibernate=yes
AllowHybridSleep=yes
SuspendMode=
SuspendState=mem standby freeze
HibernateMode=platform shutdown
HibernateState=disk

When I try to edit the conf.d/resume file with nano, it's creating a new file instead of editing an existing one.
