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
