I had a c++ program which creates .data files. I accidentally clicked its executable file directly instead of running it through an IDE. It kept on making files without opening any console. The system hanged and I turned it off by pushing the power button. Now every time I try to login, it just freezes and brings back the login page again. I already tried .Xauthority, /tmp, and lightdm solutions, but none of them work. Any solutions?
