After logging in, many elements of the GUI go black.
In the above image you'll see that the terminal is just a black box on the right. The black bar just above the unity launcher is the onscreen keyboard which is still responsive, even though it's blackened, which is true of all apps; I can close the terminal (which in the picture is the black box on the right) by randomly clicking in the upper-left corner. The same happens even for drop-downs; clicking on the wifi or the power logo on the menu bar on the top just gives me a black box.
This problem used to happen before and it would be fixed with just a simple restart. Now a restart wont't work. As you can see, I can't use the terminal, and I cant access a lot of things since the GUI will just be blacked out most of the time. I can't use my system like this. Please help.
