When ever I enter my user and password the same window comes back again and again. It wants user and password back to back. I did ctrl+alt+f3 and got terminal. I did:
apt-get update apt-get upgrade apt-get -f install apt-get dist-upgrade
all separately. I tried to remove lightdm and installed it again. But it is a matter of sorrow that I could not fix that problem.The same thing happens every time. What could be the reason behind it and what is the solution for this?
