Lubuntu Support

“sudo systemctl hibernate” works great and as expected.

GUI buttons and power button don’t work. I’ve tried messing around w the lxqt power management options, no success. What can i do?

Here’s the webpage i used to get it working via systemctl:

How do you have everything set up, what are you doing exactly, and what happens?

Ah, sorry!
I have a /swapfile of size 32GB and ram of 16GB.
Running latest kernel avail by lubuntu. Here’s my copypaste from the about:

Okay, I got it to work! Man, what a nightmare. It is 1000% necessary that any laptop’s OS (windows/linux/anything) be able to support hibernate unless u want to risk a fire from your laptop bag. I can’t speak for non-ubuntu linux distros but I think somehow people need to know that Ubuntu and it’s flavors do NOT offer laptop support by way of terrible hibernate support.

Anyway, here is what I did:

In /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla I added:

[Re-enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

[Re-enable hibernate by default in logind]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate;org.freedesktop.login1.handle-hibernate-key;org.freedesktop.login1;org.freedesktop.login1.hibernate-multiple-sessions;org.freedesktop.login1.hibernate-ignore-inhibit
ResultActive=yes

And my /etc/systemd/sleep.conf file looks like this:

#  terms of the GNU Lesser General Public License as published by the Free

[Sleep]
AllowSuspend=yes
AllowHibernation=yes
AllowSuspendThenHibernate=yes
#AllowHybridSleep=yes
#SuspendMode=
#SuspendState=mem standby freeze
HibernateMode=platform shutdown
HibernateState=disk
#HybridSleepMode=suspend platform shutdown
#HybridSleepState=disk
HibernateDelaySec=180min

Of course this was ALL AFTER the changes to initramfs and grub. Also I changed the “resume=…” FROM “/dev/nvme0n1p5” TO “UUID=213123123123132132131etc”

Hope this helps future psychopaths like myself that insist on running Ubuntu on laptops~!

And unfortunately, it’s not possible right now apparently for the Linux kernel itself to guarantee 100% support of hibernate across all devices.

More here:

Glad you figured it out for your particular set of hardware and kernel drivers, though.
