All of the windows on my desktop are missing a title bar and the decorations to maximize/minimize and close the window. I can reposition a window only by holding down the left ALT key while doing a left mouse click and drag. I can maximize/minimize a window only by using ctl-alt-keypad-5. I can close a window only by using a quit menu entry or by using the desktop toolbar on the left side.

I suspect that I accidentally hit some sort of weird key combination and set a sticky preference of some sort, but I can't for the life of me find out where to reset it. Any thoughts or suggestions?


Open CompizConfig Settings Manager and on the effects tab make sure you have the 'Window Decoration' tickbox checked like below;
