I use the Compiz Widget Layer plugin so as to have a fullscreen Terminator window a keystroke away. The only issue I have is, when I'm in the Widget Layer, notifications don't appear, so I don't come to know when someone sends me an IM in Pidgin. Does anyone have a solution that can make libnotify notifications appear in the Widget Layer?
I found that libnotify is designed in such a way as to not disturb users when they're using a fullscreen application, and that does make sense from a design point of view. So instead of using Terminator fullscreen, I got rid of its titlebar using the "Window Rules" plugin. This way it looks like it's fullscreen, and I also receive notifications properly.
