Linuxes to suspend & sleep after 20 minutes (ymmv?) by default if gdm3 is running. E.g. https://wiki.debian.org/Suspend IME it didn't matter if user was logged in to desktop or not, the mere presence of a running gdm3 process was enough to trigger the behavior unless it was disabled. My FreeBSD's without gdm3 don't see this. Obviously there's no Linux systemD in-play here, but along the lines Alexander suggests, you might try stopping any running gdm3 processes and see if the sleep behavior persists. That would at least give some hint as to the vicinity of the problem. sr.
