題目: Re: [DNG] systemd installed and running in default desktop
At this point, after some more testing and fiddling, my questions are:
1] why is systemd-shim necessary (see below, after original message)?
2] why is devuan installing xfce4-power-manager with its seemingly
unnecessary recommendation of systemd?

Running:

# aptitude why systemd (result: xfce4-power-manager recommends systemd)

# apt-get remove xfce4-power-manager

# apt-get autoremove (removes not just systemd, but also systemd-shim
and its bunch of dependencies)

# apt-get --no-install-recommends install xfce4-power-manager

Upon laptop reboot, and gui login, the xfce4-power-manager functions to
the extent that it:

1] responds to the pressing the power button with it dialog, and that
dialog will successfully logout, suspend, shut sown, reboot.

1.1] However, hibernate did not seem to work. It flickered the screen,
and did a complete shutdown.

2] The xfce4 panel has a power manager widget. All of its functions
work. Hibernate is not offered there as an option.

3] 'xfce4-power-manager --customize' has options for responding to
laptop lid closure, which are not working (tested for options
'lock-screen' and 'suspend'. Running 'acpi_listen' shows that the lid
closure is being detected. Other acpi events are recognized and function
as expected, ie screen brightness.

Re-installing systemd-shim did not change any of this, so I'm curious
why at this point its needed. I uninstalled it a second time.
