Thanks for the insight. Ok, so basically they rely on systemd/logind to
initiate the suspend, and simply inhibit/delay the suspend under certain
circumstances. GNOME (and KDE) will no longer initiate a suspend request
themselves. Is that correct?

If so, I guess setting the Suspend action ignore is a no-go, since we
don't want to brake suspend for those.

Martin, any idea how your non-GNOME/non-KDE spins, like LXDE and XFCE,
handle that in Ubuntu?

I'll probably keep experimenting with the Xsession.d script for a little
bit.

For acpid/acpi-support, we can simply make it systemd-aware, i.e. add
systemd-logind to /usr/share/acpi-support/policy-funcs:CheckPolicy().

P.S: Martin, not sure if it's related, but since some time, I get upower
timeouts after a suspend-resume cycle. E.g. upower -d simply runs into a
D-Bus timeout and the power indicator in GNOME shell stops updating. Any
idea what might be going on here? the upowerd daemon is still running,
it just seems to longer respond on any incoming (D-Bus) requests.
