[gentoo-user] pm-suspend replacement?

[gentoo-user] pm-suspend replacement?

[Alan Mackenzie]

Hello, Gentoo.

I used to have a utility pm-suspend which would suspend the current
state of the machine to RAM (or, maybe to the swap partition) and shut
the machine down to a resting state.  A keypress or mouse movement would
restore full functionality in a few seconds.

I think I lost this program in the emerge --depclean I did a couple of
months ago (the one that wanted to make my machine unbootable).

Is there anything to take its place?  In particular I want actively to
put the machine into resting state (as opposed to it happening after a
period of inactivity), and I would prefer to do this without having to
start a GUI session.

I feel there must be something like this in portage, I just don't know
how to find it.

Thanks for the help!

I'm pretty sure pm-suspend is deprecated. loginctl suspend should do the 
same thing.

`loginctl suspend`[1] if you use sys-auth/elogind. `echo mem >
/sys/power/state`[2] if not.

Thanks!

Unfortunately, neither of them works.  I tried s2ram too.  It also
doesn't work.

What they all do is suspend the system, then immediately restore it,
without the keyboard or mouse being touched.

I'm sure the kernel isn't the problem: I tried it with three kernels
going back to 5.4.97 and it failed on them all.  pm-suspend worked on
these.  Similarly, I doubt my HW is the problem.

At this stage, I think it's time to give up.  I don't want to spend hours
submitting bug reports and following up, or on endless web searches for
solutions.  The feature just isn't that important, convenient though it
would be.

Or maybe I'll try and find pm-suspend again on the web.  Maybe it had
some feature (or bug workaround) which the more modern packages are
lacking.

That's just what I did.  A web search for pm-utils found it easily
enough.  pm-suspend works again, and I'm a happy chappy - almost.  Why
was pm-utils taken off of portage in the first place?  Was there some
sort of security problem, or was it just because it hadn't been updated
in a fair while (since 2013, I think)?

That's another feature missing from portage - a systematic way of
discovering why a package has been removed.

It was removed because upstream abandoned it. It was announced in
<https://www.gentoo.org/support/news-items/2020-04-14-elogind-default.html>
which references <https://bugs.gentoo.org/659616>.

`eselect news read all | less` is sometimes helpful. 😄

It was indeed.  I think I missed it because "pm-utils" didn't ring any
alarm bells whereas "pm-suspend" would have done.
