The following boot ended up in a blank screen. The screen was not off, but just blank. Gnome was responsive: When I pressed the power button, the computer went down in sleep mode normally. When I started the computer again the screen was off. I needed to press power button five seconds to start over. Attach syslogblank.txt and Xorgblank.txt.
