I have a freshly completed install of Ubuntu 11.04, and the CD tray opens and closes all by itself. I cannot detect any pattern to when, or why.
I've rebooted, and disconnected all networking (both wi-fi and ethernet) and the spirits inside still open and close the CD Tray.
Hardware seems fine (wasn't happening with an earlier install of WinXP).
How can I determine what is process causing this, and how can I stop it?
