I have a MOST bizarre and interesting problem at the moment! After my 'unstable' machine boots.. about 2 minutes later, X will start up, with an xconsole in the corner showing 'dmesg' output, and a simple graphical login prompt in the centre of the screen forces a login before anything else can be done... If I try and kill X with Ctrl-Alt-Backspace, it immediately reloads... This one has foxed me completely!! Any ideas? Kind regards, Gavin.
