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. > > [1] <https://wiki.gentoo.org/wiki/Elogind#loginctl> > > [2] > > <https://www.kernel.org/doc/html/v5.10/admin-guide/pm/sleep-states.html#basic-sysfs-interfaces-for-system-suspend-and-hibernation> > > -- > > Get my PGP key with `gpg --locate-keys [email protected]` or at > > <https://tastytea.de/tastytea.asc>. -- Alan Mackenzie (Nuremberg, Germany).
