Legend has it that the Elders knew of a world outside Vim, a world that encompasses it and all other things. That arcana is now lost, and none can transcend our plane of existence. Vim is all we know.
I have an X1 gen 9 and sleep-on-close worked just fine with Fedora for the time I used that distro (although it was KDE, not GNOME). Every other distro I tried worked as expected in that respect.
