[SOLVED] pm-hibernate fails because of pm-utils

I'm trying to get pm-hibernate to work on my Lenovo T430. When I execute the command my laptop goes to hibernate for 1 second, power button flashes twice, laptop resumes.

From /var/log/pm-suspend.log I get the following error:

/usr/lib/pm-utils/pm-functions: line 316: echo: write error: No such device

The full /var/log/pm-suspend.log can be seen here:

These are the following lines from /usr/lib/pm-utils/pm-functions

    grep -qw "${HIBERNATE_MODE}" /sys/power/disk && \
    echo -n "${HIBERNATE_MODE}" > /sys/power/disk
    echo -n "disk" > /sys/power/state 

The last echo is where pm-suspend.log says pm-hibernate fails.

Any directions on what to do next to get my laptop to hibernate?

Re: [SOLVED] pm-hibernate fails because of pm-utils

Did you actually set up hibernation?  Why are you trying to use pm-utils (pm-hibernate)?  Pm-utils is a set of scripts that are meant to work around various bugs.  Most of those bugs don't exist any longer and pm-utils I don't think is even actively maintained anymore.

You should be using systemctl hibernate.  See the wiki to get this working.

Things work with systemctl suspend

Re: [SOLVED] pm-hibernate fails because of pm-utils

Why did you mark this is [Solved] if you didn't actually find a solution?!  I too think that suspending to RAM is good enough, and that is all I use.  Suspend to disk (aka hibernation) is pretty buggy in Linux and typically doens't work quite right anyway.

But the original question was about getting hibernate to work.  So "things work with systemctl suspend" does not address the original topic of the thread.

Re: [SOLVED] pm-hibernate fails because of pm-utils

I have a pretty small SSD but I have 16GB of ram so I made 10GB swap file in /swap and mounted it per instructions about creating swap files.
systemctl hibernate worked at that point but I like having disk space so I'll use suspend.

If battery life becomes an issue while living in suspend I'll sacrifice disk space for battery performance. When I did use pm-utils I never had an issue with hibernate, it just worked which was nice.

Re: [SOLVED] pm-hibernate fails because of pm-utils

As mentioned earlier, pm-utils is old and deprecated.  Its lack of maintenance means that it is trying to work around problems that likely don't exist.  In the event that you do find something that can be worked around with a script, systemd actually gives this functionality just in case.  See the systemd-sleep man page to learn about the arguments passed to the scripts in /usr/lib/systemd/system-sleep.  The function of that directory is almost exactly the same as what pm-utils does, but instead of running the scripts sequentially, systemd stays true to form and just runs them all at the same time.

I still have not found a really valid use for the systemd-sleep function though.  If there is something you want to hook into the suspend/sleep cycle (like a screen locker for example) then you should really be using native systemd units or acpid for that functionality.

Re: [SOLVED] pm-hibernate fails because of pm-utils

Ironically enough speaking about screen locks, this url helped me configure i3lock with suspend. Before writing my unit I tried to hook in to the systemd-sleep but it was just a nightmare. The path of least resistance is typically the best option.

Re: [SOLVED] pm-hibernate fails because of pm-utils

Interesting… I would have considered using the systemd-sleep to be much easier.  Writing a systemd service is by no means hard, but using systemd-sleep you just need a one line script.
