Hi. I'm encountering this problem too. Lately it has gone worse. Nowadays maybe even 95% of the cases "monitor looses input signal and goes to sleep, computer completely stuck, have to switch off manually by pressing power key for 7 seconds". I'm suspecting this is to blame for that I even had to already re-install Feisty once (FS went completely mad).
