Hibernate not working (Error name "org.freedesktop.DBus.Error.InvalidArgs") (Lubuntu 20.04 LTS) (Dell Inspiron 6400)

[blacksquirrel]

It appears that I am unable to hibernate my Dell Inspiron 6400 laptop with Lubuntu 20.04 LTS (dual boot with an old version of Windows). When I run the command

lxqt-leave --hibernate

, after confirming I do indeed wish to hibernate the laptop, I get the following output:

qt5ct: using qt5ct plugin
(0x7ffdecd81930) Debug: systemd: “CanHibernate” = “na”
(0x7ffdecd81930) Warning: ** Dbus error **************************

Is there any remedy? I have also tried doing it via the desktop interface, and that does not work either. Judging by the output, there is a missing interface.

In case it were relevant in diagnosing the problem, here are some of my CPU details (extracted via

lshw

):

Postscript: I have not run previous Lubuntu releases on this particular laptop, so I have no idea whether this is a version-specific problem or a more general compatbility issue.

UPDATE (17:14 BST on 18th June): it looks like the solution referenced by Noumeno is not working for me because I appear not to have a swap partition. So, I think I will need to work-out how to create one and whether it is worth the trouble (my disk is already partitioned so that I can run Windows and Lubuntu).

This is the output I got when I ran cat etc/fstab

# /etc/fstab: static file system information.
#
# Use ‘blkid’ to print the universally unique identifier for a device; this may
# be used with UUID= as a more robust way to name devices that works even if
# disks are added and removed. See fstab(5).
#
#
UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx / ext4 defaults 0 1

[i.e.: there is only one UUID displayed (I have substituted ‘x’ for the actual UUID characters)]

Re Noumeno:

I have just tried both of the solutions proposed on the relevant page. Unfortunately, neither worked (even after rebooting). Perhaps, this may be because I have a dual boot (Lubuntu and Windows)? Or maybe, my computer is not powerful enough – this is the response I got when I tried sudo systemctl hibernate

Here you go:

Also works for 20.04. As you see it’s a bit more involved than just editing one file.

Your SWAP partition must be larger than your RAM. Also, a resume from Hibernate takes longer than a cold boot. Ask yourself if you need this functionality.
