I would like to apply the Toogle Invert Effect when I start my system.

So, I need to know how to call this KWin effect using the terminal.

OBS.: I'd tried xte "keydown Meta_L" "key i" "keyup Meta_L", but didn't work.

The effect itself does not seem to do anything on my computer, but I think you can enable/disable it through dbus in this way:


dbus-send --print-reply --dest=org.kde.KWin /Effects org.kde.kwin.Effects.loadEffect string:"invert"


dbus-send --print-reply --dest=org.kde.KWin /Effects org.kde.kwin.Effects.unloadEffect string:"invert"
