I remember having this issue on an old PowerBook G4 15” (which I no longer have). It was related to the screensaver starting. The screensaver would start but instead of displaying the graphics, it would black-out the screen. Neither keypress nor mouse movement would return to the desktop. I recommend removing your screensaver. Additionally, try disabling the auto-dim/auto-off for the display. Dave

Is there any reason why X would start normally, but then a few hours later, crash with the same old problem? Scenario: I fixed a lot of my issues over the weekend, by using "X -config" ,and then used the auto-generated xorg.conf, but first commenting out things not display-related, and the extra monitor that it added. Then the system booted up, and even started X! Morning comes: The battery was fully charged. Black screen is back. j
