Hi. I inherited a linux system which I have used solely for surfing, email and desktop games, until recently, when it wouldn't boot up into the usual login screen. Now messages appear: "Failed to start the X server...", "Fatal server error: could not open default cursor font." Eventually, (still in the black screen) it asks for username, password, and then root@localhost #. This is where I am stuck. I have tried many words and numbers, but none work. Can you please help me? I would be most grateful.
