i know that there are many replicas of the same question, but I am stuck with this problem, as many others, with the only difference that my ubuntu is running on a virtual machine.
When i try to login, the system just gives me back the login screen, asking for the password.
I have tried to:
mv .Xauthority .Xauthority.bak
and it did not work.
I upgraded and updated the packages but nothing. I also upgraded the Nvidia drivers as many had problems because of it.
Can someone please help me solving the problem?
