Xorg log
Problem: when connecting two displays and starting X, both screens are just
black with a static (not blinking) text cursor in the top left corner. With
only one display (does not matter which one was disconnected) X starts normal
after reboot. Restarting X after connecting/disconnecting a display does not
change the behavior, the system has to be rebooted.
