Summary: KDE reads the Version property of org.freedesktop.systemd1.Manager
interface and hides the Suspend/Hibernate buttons if it is not new enough, but
systemd-shim doesn't implement that property.
Attached is a patch for systemd-shim to workaround this issue.
Looking through ./powerdevil/daemon/backends/upower/powerdevilupowerbackend.cpp
there are 2 implementations,
one using the login1 interface, another using upower:
if (m_login1Interface && checkSystemdVersion(195)) {
...
} else {
if (m_upowerInterface->canSuspend() &&
m_upowerInterface->SuspendAllowed()) {
...
}
upower in its latest version doesn't support suspend/resume anymore so we'd
want to use the login1 interface.
This seems to be provide by systemd-shim, and says that Suspend is supported:
$ qdbus --system org.freedesktop.login1 /org/freedesktop/login1
org.freedesktop.login1.Manager.CanSuspend
yes
$ qdbus --system org.freedesktop.login1 /org/freedesktop/login1
org.freedesktop.login1.Manager.CanSuspend
yes
KDE also does a version check on the interface though, which is this code:
QDBusInterface systemdIface("org.freedesktop.systemd1",
"/org/freedesktop/systemd1", "org.freedesktop.systemd1.Manager",
QDBusConnection::systemBus(), 0);
const QString reply = systemdIface.property("Version").toString();
QRegExp expsd("(systemd )?([0-9]+)");
systemd-shim doesn't implement Version in org.freedesktop.systemd1.Manager:
$ dbus-send --system --print-reply --type=method_call
--dest="org.freedesktop.systemd1" /org/freedesktop/systemd1
org.freedesktop.DBus.Properties.Get string:"org.freedesktop.systemd1.Manager"
string:Version
$ qdbus --system org.freedesktop.systemd1 /org/freedesktop/systemd1
org.freedesktop.DBus.Properties.Get org.freedesktop.systemd1.Manager Version
Error: org.freedesktop.DBus.Error.InvalidArgs
No such property 'Version'
According to the documentation[0] the Version property is NOT part of the API,
so KDE would be wrong for using it...
However as a quick workaround I patched systemd-shim to provide the Version
property:
$ apt-get source systemd-shim && cd systemd-shim-8
$ quilt import ~/add-manager-version.patch
$ quilt push -a
$ dpkg-buildpackage -us -uc
$ sudo dpkg -i ../systemd-shim_8-3_amd64.deb
Reboot (the menu entry would show up after restarting dbus and logout/login,
but the Suspend method would give permission denied,
probably more things need to be restarted).
Now there is a Sleep entry in the Leave menu!
I have reported a bug at upstream KDE about using the 'Version' property:
