I'm new to ubuntu and took many days trying to solve a problem I'm having.
I searched the Internet and I have not found anything concrete that can fix it so this is my problem:
When I try to open the terminal, it is closed immediately and does not show me anything. I tried to run with CTRL + ALT + F1 or F2, and CTRL + ALT + T, but I get nothing and the moment it opens, it closes.
One thing I've discovered is that if I connect with the guest account then I can access the terminal.
