Description Scott Howard 2009-07-09 01:08:01 UTC 
Steps to reproduce:
1. Call the inhibit functions either by using "gnome-power-manager-inhibit test" or following the examples at the FAQ or bug 472812. (/usr/bin/gnome-power-manager-inhibit)
2. The Inhibit function will crash

An example Python script which works in 2.24 but not in 2.27:
#!/usr/bin/env python
import dbus
bus = dbus.SessionBus()

devobj = bus.get_object('org.freedesktop.PowerManagement',
'/org/freedesktop/PowerManagement/Inhibit')
power = dbus.Interface(devobj, "org.freedesktop.PowerManagement.Inhibit")
cookie = power.Inhibit('application name', 'reason')
power.UnInhibit(cookie)



Stack trace:
Traceback (most recent call last):

+ Trace 216362

  • File "/usr/bin/gnome-power-manager-inhibit", line 34 in <module>

    message, timeout)
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "Inhibit" with signature "ss" on interface "(null)" doesn't exist 


Other information:
Additionally, I have not been able to get the inhibit applet to work at all in GPM 2.27. When I click on it on the panel, nothing happens. Nothing shows up on gnome-power-manager --no-daemon --verbose or across the dbus-monitor --session "type='signal',interface='org.freedesktop.PowerManagement'" when I attempt to use the inhibit applet in the gnome panel. If these are two bugs, they should be separated out - but I have a feeling that they are related (but no data to back that up yet).
