After installing Kali, everything was running smooth, suddenly sqlmap did not work, meaning it won't launch; same for regular terminal it starts loading but does not open... When i try to open my terminal and my root terminal, happens nothing but a loading sign in the upper bar for a little while and then disappears. I'm sorry if this is an easy problem to be solved but i didn't found the answer or any similar problem. Already updated with ctr+alt+F1, nothing changed.... Running Kali 2.0 (Sana) HDD, Intel Core i5, 6gb Ram... any help would be deeply appreciated
