Hi,
In gnome-control-center application, one can configure its laptop to go
in suspend mode when Energy goes very low. However this is only
possible when laptop supports Hibernation, as cc-power-panel.c:1945
queries DBus:
result = g_dbus_connection_call_sync (connection,
"org.freedesktop.login1",
"/org/freedesktop/login1",
"org.freedesktop.login1.Manager",
"CanHibernate",
NULL,
NULL,
G_DBUS_CALL_FLAGS_NONE,
-1,
NULL,
NULL);
Instead of asking for "CanHibernate", should not it be asking for
"CanSuspend" feature (or both?). In my personal case, I do not have any
SWAP so hibernation is not available, but suspend is:
$ qdbus --system --literal org.freedesktop.login1
/org/freedesktop/login1 org.freedesktop.login1.Manager.CanHibernate
"na"
$ qdbus --system --literal org.freedesktop.login1
/org/freedesktop/login1 org.freedesktop.login1.Manager.CanSuspend
"yes"
I would like to suspend computer instead of shutting it down when
Energy is critical. Is it the right place to discuss about it, or
should I ask somewhere else?
Thanks!
