what about Ubuntu 24.04?

I have update ubuntu yesterday. But no buttons in menu

By the extension it is supported. However the system is buggy. It is not clear (to me) atm why is it buggy on half of the machines.

For example: I have a Lenovo Legion 5 machine with AMD+NVIDIA configuration. Sometimes hibernation appears, sometimes not. I have a ThinkPad too which is just a simple 10th gen Intel configuration. On that machine the old method (create/resize swap, create pkla files, modify and add it to grub). But the Legion machine cannot hibernate with this workaround. I mentioned this problem in this closed issue and found a partial solution. As I mentioned that even with these solutions sometimes hibernation disappears. So take a look. Btw ignore Loping151's workaround, because it is a KDE specific thing.

Same issue here. A systemctl hibernate works fine after the setup, the /sys/power/resume contains the major:minor version of my swap partition but the menu does not appear.
One thing I'm not sure how it's changed since 22 to 24 is the grub line to activate the hibernation.

I have a GRUB_CMDLINE_LINUX as opposed to the example the extension refers to where it is suggested GRUB_CMDLINE_LINUX_DEFAULT. I'm not sure this has a direct impact

Can you please include an extract of journalctl -f showing the menu being opened.

I am currently experiencing the same problem, although the buttons only vanish after a few seconds. Directly after startup they are available.

Here's a log extract:

Had the same issue, the polkit rule described here solved the problem: https://www.reddit.com/r/Kubuntu/comments/1c2frkd/enabling_hibernation_on_2404/

Create/edit the file /etc/polkit-1/rules.d/10-enable-hibernate.rules with the following contents:

polkit.addRule(function(action, subject) {
    if (action.id == "org.freedesktop.login1.hibernate" ||
        action.id == "org.freedesktop.login1.hibernate-multiple-sessions" ||
        action.id == "org.freedesktop.upower.hibernate" ||
        action.id == "org.freedesktop.login1.handle-hibernate-key" ||
        action.id == "org.freedesktop.login1.hibernate-ignore-inhibit")
    {
        return polkit.Result.YES;
    }
});
