Hello everyone, The suspend-then-hibernate option of elogind tries to detect the type of wakeup that the system supports, and to that end reads /sys/firmware/dmi/entries/1-0/raw. However that file only exists if the kernel module dmi-sysfs has been loaded, which doesn't seem to be the case by default on my Guix system.
If that doesn't work out, it falls back to a custom implementation that wakes up the system periodically to check the battery status, however that is also broken for some other reason™ on my system, leading to an instant hibernation. Loading dmi-sysfs manually solves this issue, but I don't know how to do that with the elogind-service-type implementation. Best, -- Josselin Poiret
