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. > [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).
