I decided to build xfce4-session from ports, and add a debugging printf() between these lines to see exactly which error dbus was returning. So I installed it, and selected 'Quit' from the menu while tail-ing the error log... and the shutdown/reboot buttons came up enabled!! It all seems to work fine now. Does this mean there's something wrong with the package builds? I guess I could file a PR. >> >> /* if we receive org.freedesktop.DBus.Error.UnknownMethod, then >> * we are allowed to shutdown/reboot the computer via HAL. >> */ >> if (strcmp (error.name, "org.freedesktop.DBus.Error.UnknownMethod") == 0) >> >> So out of curiosity I tried this manually and got the 'correct' error: >> >> $ dbus-send --system --print-reply --dest=org.freedesktop.Hal >> /org/freedesktop/Hal/devices/computer >> >> org.freedesktop.Hal.Device.SystemPowerManagement.ThisMethodMustNotExistInHal >> Error org.freedesktop.DBus.Error.UnknownMethod: Method >> "ThisMethodMustNotExistInHal" with signature "" on interface >> "org.freedesktop.Hal.Device.SystemPowerManagement" doesn't exist >> >> Now I don't claim to understand much of this, so any help would be >> greatly appreciated.
