I just downloaded Cairo Dock from the Synaptic Manager and its there, it just is invisible. When i tried to click something in the panel at the bottom, something else comes up and it dawned on me it was something on the cairo dock that was invisible. I right clicked on the regular panel trying to access a minimized window and the cairo dock options showed up. So its THERE, it just is invisible where i CANT see it. I have Cinnamon on my laptop and the cairo dock from the synatpic manager works fine. How can i get it to show up in mate?
