Hi all!

I want to control my computer using a remote control. It would be handy to use kwin's zoom effect to see what's happening on the desktop when I lie on my bed.
Unfortunately, I was not able to find a command or dbus-interface to enable/disable the effect or to control it.

Does anyone know how to do that?

Thank you very much!

There is a plasmoid that will do that. It's called the Toggle Compositing plasmoid. I know Kubuntu 8.10 has packages and I think Open SuSE does too.
...but even this plasmoid edits kwinrc and reloads the config to enable compositing:

Code: Select all

    QDBusMessage message = QDBusMessage::createSignal("/KWin",
                                                      "org.kde.KWin",
                                                      "reloadConfig");
    QDBusConnection::sessionBus().send(message);

Thank you for your answer, but that does not solve my problem...
I want zoom in/out by pressing buttons of my remote control.

My last idea was to set up global shortcuts like CTRL-ALT-+ and simulate these on pressed remote buttons. I've tried to use irxevent, but KWin seems to ignore the generated events...

The relevant part of my lircrc looks like the following:

Code: Select all

begin
    prog = irxevent
    button = snapshot
    config = Key ctrl-alt-KP_Add RootWindow
end

Has anyone solved this?

You can use xsendkeys from the lineakd package to send fake keyboard events that should work even with global shortcuts.

Thank you very, very much, Seli! That works perfectly!

You made my day!
