If you read the logind.conf man page carefully, you'll see that logind
does respect low-level block requests. So if xfce4-power-manager takes a
blocking lock on handle-lid-switch it can implement it's own policy.
I just tested in a VM and xfce4-power-manager does take a proper
inhibitor lock:
$ systemd-inhibit
Who: NetworkManager (UID 0/root, PID 586/NetworkManager)
What: sleep
Why: NetworkManager needs to turn off networks
Mode: delay
Who: xfce4-power-manager (UID 1001/test, PID 2138/xfce4-power-man)
What:
handle-power-key:handle-suspend-key:handle-hibernate-key:handle-lid-switch
Why: xfce4-power-manager handles these events
Mode: block
Who: ModemManager (UID 0/root, PID 561/ModemManager)
What: sleep
Why: ModemManager needs to reset devices
Mode: delay
3 inhibitors listed.
I've used xfce4-power-manager-settings to instruct it to do nothing on
lid-close. Closing the lid, nothing happened. So everything is working
as expected. For xfce4-power-manager to successfully take an inhibitor
lock, it needs to run in an active, local session. You can check that via
$ loginctl show-session $XDG_SESSION_ID
Id=5
User=1001
Name=test
Timestamp=Tue 2017-03-28 06:00:00 CEST
TimestampMonotonic=33951653
VTNr=7
Seat=seat0
Display=:0
Remote=no
Active=yes
State=active
Both logind and xfce4-power-manager work as expected. If you still have
something else reacting to power events, I would check if you have
something like acpid running which might interfere. This is no longer a
logind bug though, so closing this report.
Regards,
Michael
