Since I have upgraded my working Lucid PC to Maverick I am unable to log in as a normal user. I can only login as root. If I log in as a normal user the log in screen disappears and reappears with the sound effects. If I type the wrong password then I get authorization failure and back to the log in screen as normal. Even then as root if I try to run some programs it will return to the login screen. The display seems to be fine - it is the onboard S3 - no special drivers.
Please help - I am scared to upgrade my other machines!!
