I went into CompizConfig Settings Manager to disable a setting in the Grid plugin (Snap windows back to original size.)

As soon as I checked it off, the screen flickered for a moment, the launcher disappeared, all windows lost their borders and clicking on them did nothing. Whenever I try to log into that account on regular Unity, I either see my desktop and nothing else, or my desktop along with the taskbar up top with Nautilus's menus. (I can't provide screenshots ; printscreen button does nothing.) If I open a window with the Nautilus menu, it has no borders, and I can't click on anything. The only way I've found to interact with anything in this state is to bring up the virtual terminal with Ctrl+Alt+F1, but I have no clue how to fix anything from there.

I can still log into Unity on all other accounts, and I can still use Unity2D on the affected account. How do I get Unity up and running again? Thanks.
