Ubuntu installed some updates, and after the restart, I cannot log in. It seems to accept, but then beeps and returns to the login screen. All of the users, including guest do the same thing.
I was looking at some other posts here, and tried some of the suggestions without success. I looked at the .xsession-errors file but I don't understand the error:
X Error of failed request: BadValue (integer parameter out of range for operation)
