Public bug reported:
Binary package hint: gnome-power-manager
When the pm-utils scripts pm-suspend/pm-hibernate trigger a low-level
inhibit this triggers failures from hal back to gnome-power-manager
which do not contain any error strings. This is not handled by gnome-
power-manager and the errors are silently ignored (from the users point
of view), leading to a log entry:
Hibernate failed in a horrible way!
If we look at hal_gpower_pm_method_void() we can see that if the dbus
call is successful, but the reply is a non-zero retval with no error
string associated with it we will end up with:
ret = 0
retval != 0
*error == NULL
This in turn results in us producing a warning to the log and nothing
for the user. This result form seems to occur when the hal runs pm-
suspend/pm-hibernate and those run but exit non-zero:
hal_gpower_pm_method_void(...)
{
[...]
time (&start);
ret = dbus_g_proxy_call (proxy, method, error,
G_TYPE_INVALID,
G_TYPE_INT, &retval,
G_TYPE_INVALID);
/* we might have to ignore the error */
if (error != NULL && hal_gpower_filter_error (error))
return TRUE;
if (retval != 0)
g_warning ("%s failed in a horrible way!", method);
[...]
return ret;
}
Losing this information seems incorrect.
