For a while gnome worked just fine but now all it shows is the background. I can still log out and open the terminal with the keyboard but I can't figure out how to get anything else to work. I have an Acer Aspire. I also can't get the tweak tool to open at all. I'm not too good with computers but I learn fast, so if anyone knows how to fix this or if I need to give more info about the computer, please help.
