Hi. With Xubuntu 15.10 (was same w/ 15.04) when suspend is initiated
through inactivity, it fails with the quoted text:
"GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Permission
denied".
I've tried this
[https://askubuntu.com/questions/627356/xubuntu-15-04-cannot-suspend-when-inactive]
fix but it didn't help.
I suspect that this
[https://bugs.launchpad.net/ubuntu/+source/xfce4-power-manager/+bug/1441460] is
close but irrelevant?
Seems to fail the same when powered or on battery - I haven't noticed a
difference in any case.
Any thoughts / guesses appreciated. When I come back to it and wiggle
the mouse, hit the keyboard, or sometimes hit the power button, it comes
back to the session login screen then returns with that failure warning.
So I suspect it has been sitting there unsuspended but with the screen
off.
edit: just noticed I'm using v1.4.4-4ubuntu (per software manager);
given we're not on 1.5.2 is there a reason why this hasn't been upgraded
as part of xubuntu 15.10? Cheers.

I had this exact error in Xubuntu 16.04 and fixed it with this solution:

The fix in the link (http://askubuntu.com/a/851760/83302) worked for me
as well on Xubuntu 16.04. Incidentally, someone on the Ubuntu-devel-
discuss mailing list reported what I think is the same bug and
workaround and suggested a more permanent fix:

The error message "GDBus.Error:org.freedesktop.DBus.Error.AccessDenied:

caused by a separate bug.
Bug: NetworkManager.Sleep access denied
The access denied error is caused by xfce4-power-manager attempting to
call org.freedesktop.NetworkManager.Sleep, but access is denied by
Network Manager's polkit policy. This bug could be fixed by creating a
polkit rule to allow xfce4-power-manager to call the Sleep DBus message.
However, a better fix would be to not call
org.freedesktop.NetworkManager.Sleep at all, at least when using logind
for suspend, because Network Manager automatically sleeps by using a
logind suspend inhibit delay. I reported this bug on the Ubuntu bug
tracker https://bugs.launchpad.net/ubuntu/+source/xfce4-power-
manager/+bug/1713224.
Bug: Inactivity sleep mode on battery when hibernate is disabled
Not suspending when on battery is a separate bug. It is a duplicate of
Bug 12497. It is caused by a combination of things:
* The default sleep action on AC is suspend. The default sleep action on
battery is hibernate. (see xfpm_xfconf_class_init() function in xfpm-xfconf.c)
* Hibernate is disabled by default on some systems.
* In xfce4-power-manager-settings, there is a GComboBox to select the sleep
mode on battery. This combo box displays only one item, suspend, because
hibernate is disabled. The "inactivity-sleep-mode-on-battery" setting is only
updated after the GComboBox changed signal fires. The changed signal never
fires if there is only one item in the combo box, so selecting suspend does not
change the sleep mode from hibernate.
To reiterate, xfce4-power-manager attempts to hibernate on an inactivity
timeout even when hibernate is disabled, and you cannot switch to
suspend using the settings GUI. If hibernate was enabled and suspend
disabled, then a similar bug would happen during inactivity timeouts on
AC.
There are a number of potential solutions to this bug.
1. In xfce4-power-manager intelligently select a default value for
"inactivity-sleep-mode-on-battery" and "inactivity-sleep-mode-on-ac"
when these settings are not explicitly set. The value
