I haven't used my laptop for more than a week. Today I tried to login to my existing account, but after I entered my password a black screen is shown. I waited for couple of minutes to see if anything happens, but nothing happens.
After that I turned off my laptop (by pressing the button) and turned it on. I logged in successfully with Guest User.
I also managed to login to my account by pressing Ctrl + Alt + F1 and logging in through terminal. I checked some suggested solutions and tried some of them, but nothing helped. I tried updating/upgrading software through terminal, but still I can't login.
I know the information I provide is very limited, but if you have any idea how I could get more information about the problem, please let me know.
Thank you in advance :)
