I did about ~16 reboots and it blanked out on me only 2 times. I was using a script to reboot and/or startx. One time I'm not exactly sure if X was started, so it might have blanked out on a "startx". The other time I'm fairly sure X wasn't started, so it blanked out on a terminal login. Both of the blank outs were different than the ones with gdm started. Pressing ctrl+alt+f# changed nothing on the screen; the screen seemed almost completely off (no or little backlight). A few seconds after pressing the power button the shutdown splash screen would show, but this time it was _very_ faint. Usually, when gdm is enabled, pressing ctrl+alt+f# would "refresh" (or mode/resolution change) the screen, but it would still be blank. Also the backlight still seamed to be on and at full brightness (although, still displaying black). Well, I don't know what to say, it's the strangest of problems.
